Troubleshooting slow AirDrop?

Hello,
I am expereiencing very slow AirDrop speeds between my Mac Pro and Macbook Air (both on Yosemite, but has always been slow).
I am seeing about 1.5 megabytes/sec...
What are some steps I can take to troubleshoot why the speed is so slow?

Hi appleclaire:
1) Try using Disk Utikity to 'Repair Permissions' and 'Verify/Repair' Disk. You may need to start from you system DVD ie:
"To use the Install Mac OS X disc, insert the disc and restart your computer holding down the"C" Key OR (Option key and then select the Install Mac OS X disc and click the arrow).
Open Disk Utility.
In the Mac OS X Installer, choose Utilities > Open Disk Utility.
Select the startup disk you want to repair in the list of disks and volumes, then click First Aid.
Click the button to verify or repair the disk or disk permissions.
Check the S.M.A.R.T. status of your hard disk at the bottom of the window. If it shows "Verified," the disk has nothing wrong at this time. If you see "About to Fail" in red letters, back up your files on the disk as soon as possible and replace the disk."
2) Get the free program ONYX and use it to perform 'optimize system- complete' and run ALL the cron scrips - Daily/Weekly/Monthly.
3) You may need to defrag you disk with programs like iDefrag, Techtool Pro 4, Drive Genius, or Speed Tools.

How to track the flow of Sharepoint SSRS report requests to troubleshoot slowness

How to track the flow of requests of Integrated SSRS report links in Sharepoint.
We are using SSRS with Sharepoint for reporting purpose. The issue is some of the reports get generated fast and some other reports generation is very slow. When the sql query of these reports RDL file is executed, the records are shown fast.
Also even on clicking the "Add Subscription" link of "Manage Subscriptions" of a report is very slow for some reports, while it is fast for other reports.
I tried enabling SQL profiler to track the requests. I have checked profiler log for the SQL statements with exec sp_executesql. But they are not helpful.
Pls advice on how to track the request of flow of SSRS report request in sharepoint and how to troubleshoot the slowness in "Add Subscription" link, response of some reports.

Hi Pradeesh,
According to your description, my understanding is that you want to track SharePoint SSRS report requests to troubleshoot the performance.
Developer dashboard is very help full while troubleshooting the issues related to performance in SharePoint 2013. You can have a try.

Need help troubleshooting slow startup after installing apps

I'm relatively new to OSX (though not new to computer administration and Unix/Linux) and I need some guidance troubleshooting my slow booting Macbook.
I've got a vanilla Macbook that can installed with 10.5.5 and I've since done the upgrade to 10.5.6. I didn't have any problems until I started installing some heavier apps like the Adobe CS3 suite and MS Office (I know, I should get iLife, but I have an available license of Office.)
Since doing these installs, it has noticeably, but not drastically, slowed the start-up time of my mac. The slow down starts in the blue screen part of startup and is most noticeable as the dock and the menus load.
(I've read about Searchlight indexing, which would make sense since these are both big suites, but it's had several hours of run time to do this and many reboots and it's still a problem.)
I have my suspicions that Adobe is mostly the culprit here, but I'm not sure where to look for start-up logs and configuration info. Are there any apps out there like Start Up Control Panel (www.mlin.net/StartupCPL.shtml) for OSX? Are there any places that would be a good place to start looking? I basically want to try to make sure that only the necessary stuff is loading at start-up and and none of that "helper app" crap that was so common in windows environments.

Troubleshooting slow down on G5 PowerMac (PPC May 05)

My PowerMac is slow to load internet pages and slow to function when moving around in applications. I try to keep only the essentials running and limit the number of windows open, but to no avail. I just tried to burn a DVD, and it didn't burn evenly. The DVD catches and slows down randomly.
I don't know where to begin troubleshooting this issue. I've tried changing the performance in Energy Saver Pane of System Preferences, but that hasn't helped. My OS is up to date. If this is a processor thing or I need more RAM, I really just don't know how to proceed.
Any advice or troubleshooting suggestions would be extremely helpful.

Troubleshooting slow response to email via vpn

I've just adopted a vpn 3000 concentrator, and am totally learing this, so my apologies.
What could be reasons within a VPN enviroment that people are having slow response to email. (excluding issues with servers)
From a network perspective I can trouble shoot slow response, but how would a vpn enviroment be any more different to troubleshoot.
Naturally VPN is going to be much much slower, but taking 10 minutes for multiple users to get their email seems odd. LAN users get there email within seconds

Hi:
I'll tell you, I used to have the exact same problem at my last company.
We had an Exchange server for email and everyone used Cisco's VPN client.
Email was so slow, it was ridiculous sometimes. Everything else was OK, though. Other applications were OK, and network management was also good. It was just Exchange.
I know that Exchange is notorious for being delay intolerant, but this was bad! and it seemed to get worse with time.
Anyway, I dont know if you have done any troubleshooting yet or not, but you would definitely want to focus on the MTU settings for the VPN connection. Remember that IPSec adds overhead that may cause the ethernet frame to exceed the network's allowable MTU, so the packets get fragmented and reassembled at the receiving end. This can be a very slow process. And some applications are not very tolerant of fragmentation, like SQL and, I think, Exchange, too.
The problem with client VPN is that you would have to adjust each user's PC MTU. With site-to-site VPN, you can, of course, set the maximum segment size of the entire tunnel, so all users sitting behind the tunnel will be forced to conform to the tunnel's stips.
But you can try doing that on a few PCs to see if anything changes. I changed the PCs MTU using freeware called DR. TCP/IP. You can download it for free and it will allow you to change the PCs MTU very easily -- just a few keystrokes, instead of having to go into the registry and get stupid with Windows.
Change the output segment size for the PC to, say, 1400, and see if that improves anything. You would also want to change it on the 3000. I forgot how to do it on the 3000.

Troubleshooting slow startup of JavaFX app

I made a simple Hello World example from the Efxclipse tutorial on JavaFX. It takes 12 Seconds to start. After searching the internet I found:
Deploying JavaFX Applications: Troubleshooting | JavaFX 2 Tutorials and Documentation
I can pass "-Djavafx.autoproxy.disable=true" or "-Djavafx.autoproxy.disable=false" or "-Djavafx.autoproxy.disable=nonsense" to make is start fast.
a) Is the parameter documented correctly? Because whatever I pass after the "=" does not matter. However, if I pass "-Djavafx.autoproxy.enable" then it starts slow.
b) Why do I need the parameter at all, if the build.xml already contains
<manifest>
<attribute name="JavaFX-Feature-Proxy" value="None"/>
</manifest>
? Does ant not work correctly?
c) I downloaded also the JavaFX Sample applications from oracle (javafx_samples-2_2_40-windows). While SwingInterop.jar starts fast, the BrickBreaker.jar takes the same amount to start. If oracle does not even manage to come up with a jar that starts fast I think I have a serious deployment issue.
Any solutions to this?
Best,
Gunter

Hello All,
Thanks for giving advise and solution.
I logged a job with oracle support and they confirmed that this is a bug in Solaris. Below is reply from oracle.
"Thank you for the details. This is indeed a bug as OS level, a Solaris bug and it is best described in note: Oracle Database Startup And SGA Value Change Takes A Very Long Time To Complete (Doc ID 1475621.1). The bug is currently under investigation and it is being worked on. "
Although a workaround solution also applied to our env and its working fine now.

Hey, thanks for the tip!
I tried adding the bit to modprobe.d, but no results. I believe the issue is with encryption, and this is why:
Until recently, I'd used WEP, but had to change it to WAP2 . I noticed issues shortly afterward, and just today, I fiddled around some more. Unencrypted download speed came in around 17-20 mpbs, WEP was 9-13. But, somewhat unfortunately, when I switched back to WAP2 to confirm the issue, I connected at about the same speed as the other encryptions. So it seems to be faster now, but I can't say why.
I suppose another explanation would be that changing the type of encryption reset something that needed resetting with my router.
Any input is welcome.
Here is this-
# iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"onliner"
Mode:Managed Frequency:2.417 GHz Access Point: C4:3D:C7:92:07:2C

Troubleshooting slow Windows logon time with MAP - How?

Our company recently had a presentation by an MVP and just as a comment he mentioned they had used MAP to find out why a computer had slow logon time. By using MAP they had identified the source to be a setting in a group policy. He did not explain more
about the subject.
I have downloaded MAP-toolkit now and I am not sure how to proceed. I have completed Inventory where I simply specified the one computer with slow logon time. 100% inventory success. Then I ran the Performance metrics and had it run for 1 hour. The computer
was restarted during the one hour so that we would hopefully register the slow logon
After the Performance Metrics collection was complete, we check the results, but cannot find where in the report to look for any issues.
Come to think of it, maybe the Performance Metrics is the wrong report..? Maybe another collection and report should be used for this, but I can't see which one.
Kthxbai

there are
manygoodblogarticles around that
describe possible troubleshooting scenarios. Which one will prove the best will highly depend on he root cause of the issue.
Allthough MAP might offer quite a lot of info on boot and login phase, I think it might not be the best way to go on this.

Help troubleshooting slow user login

for the past week i've been having a problem with slower then normal login to my user account. (the top menu bar loads in slices very slowly)
login in safe mode and to another user account is much faster so i can narrow it to something in my start-up items/extensions.
what's the best way to figure out the problem: should i be disabling the login items in my user account control panel or should i be looking for something in the user/library folder?
btw, i repaired disk permission and deleted cache files using first macjanitor (which seemed to hang so i force quit) but then i followed up with onyx.

Jimyyz,
Most times that I've seen this, the problem was caused by a bad cache file in the main Library folder. Look in /Library/Caches for all cache files associated with this account (most of these will have the account's UID appended to the name: "501," 502," "503," etc.). If you don't know the account's UID, check that user's "properties" in Netinfo Manager.
Good luck!

Troubleshooting Slow Virtual Machines

Friends:
I am struggling with very slow virtual machines.
I have Windows Server 2012 installed on a Dell T620. It has two Intel Xeon E5-2650 2.00GHz chips (20M Cache, 8.0GT/s QPI, Turbo) and 64 G of 1600 MHz RDIMMS. It is set up with two RAID arrays (RAID 1 for OS with two 300G 10k SAS drives; RAID
5 for server stuff with four 600G 10k SAS drives) running on a PERC H710 Adapter RAID Controller (512MB NV Cache).
There are two virtual servers running on the box. One is the domain controller and the other hosts a SQL-based practice management program. The "physical server" hosts HyperV etc.
There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB.
HyperV has two virtual switches ("RDS Virtual" and "Intel I350 Gigabit Network Connection - Virtual Switch"). (I don't actually know why it is set up that way.)
I wonder whether anyone can help me trouble-shoot my poor performance?

Hi MicahS,
" There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB. "
First , I would suggest you to try to allocate more host CPU resources to these VMs .
To narrow it down , you can use performance monitor to check specific host resource .

Software to help troubleshoot slow machine?

I have a MBP with 16GB RAM, SSD and 2.7Ghz Core i7. I don't know why but after a few hours of the computer running, it will start struggling to respond. Flipping between browser tabs gets slow and when I swipe across my Dock icons, they are slow to catch up on animation.
I don't see anything in particular with Activity Monitor. Is there any other software that can help pinpoint what is drawing on resources so much?

When you have the problem, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select

Need help troubleshooting slow Tomcat

I have a servlet that takes a keyword and passes it to a second servlet, who searches a database.
Everything is working fine on the development server. It takes a few seconds to search the database, but that is acceptable.
I have moved everything to the production server, and there, it takes minutes to do the same search. I've set the virtual memory to be the same as the dev server (3024 mb) but that is not being used anyway.
If I start a search and then click stop, or even exit my browser (I'm thinking that should kill my request, is that right?), Tomcat continues to occupy the cpu for minutes (I'm guessing 3-4).
I don't know what Tomcat is doing, or how to find out. Can somebody offer a suggestion for me?
Dev server:
Xeon 1.7 GHz
1,024 Mb RAM
Windows2000
Tomcat 4.1.24
Prod server:
PII 399 MHz
1, 024 Mb RAM
WindowsXP
Tomcat 4.1.27 as a service

Gotta use a profiler like JProbe or OptimizeIt to find
out, plus a packet sniffer to monitor the network
traffic.Uh. A profiler?
After a little bit of searching, I see that there are a few open source profilers available. Any input on them? Cougaar, JMemProf, JAMon... are they all pretty much the same?

Report in Designer fast, in Viewer extremely slow

Hi.
I have a report which connects to a SQL Server backend, calling 3 stored procs which deliver the data needed for the report. However, when I execute the report in the Designer (the web app uses CR 9, but I'm testing it with CR 2008 that came with VS 2008) it takes approx. 20 seconds to return with the data - yes, the query takes rather long...
When I run our web application and call up the same report, using the same parameters and connected to the same database, the Viewer sits there for about 10 minutes before finally showing the report. I've been trying to determine the cause of this but have come up empty so far.
The report itself is a fairly simple report: headers, a parameter overview (the report uses parameterized queries), the data, and no subtotals, no subreports, no formulas.
Why is this taken so long using the Viewer? Apparently it can be fast(er) since the Designer comes within 20 secs WITH the correct data!
I've tried a couple of things to see if I could determine the cause of the bad performance, but so far I've had no luck in improving performance whatsoever. The only thing left would be redesigning the underlying stored proc, but this is a rather complex stored proc and rewriting it would be no small task.
Anybody has any idea on what to do next? Our customers are really annoyed by this (which I can understand) since they sometimes need to run this report a couple of times a day...

Interesting article. Unfortunately, trying several of the suggestions made, it didn't improve the report's performance. No noticeable difference in either Designer or Viewer.

This part is not relevant. Loading the report isn't the problem (first query being executed under 0.5 seconds after starting the report); as I'll explain further at the end of this reply.

The only OLE object is a picture with the company logo. It is visible in design time though, so I guess that means it is saved with the report?
> u2022 The subreport option "Re-import when opening" is enabled (right click the subreport(s), choose format subreport, look at the subreport tab). This is a time consuming process and should be used judiciously.
The report contains no subreports.

Tried that. It was set to the Microsoft XPS Document writer, but checking the 'No printer' option only made a slight difference (roughly 0.4 seconds in Designer).
> u2022 The number of subreports the report contains and in which section the subreports are located will impact report performance. Minimize the number of subreports used, or avoid using subreports if possible. Subreports are reports within a report, and if there is a subreport in a detail section, the subreport will run as many time as there are records, leading to long report processing times. Incorrect use of subreports is often the biggest factor why a report takes a long time to preview.
As stated before, the report has no subreports.
> u2022 Use of "Page N of M", or "TotalPageCount". When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page of the report before it displays the first page. This will cause the report to take more time to display the first page of the report
The report DOES use the TotalPageCount and 'Page N of M' fields. But, since the report only consists of 3 pages, of which only 2 contain database-related (read further below) I think this would not be a problem.

For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports. SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.

All of the above points become moot if you know the structure of the report:
3 pages, no subreports, 3 stored procs used, which each return a dataset.
- Page 1 is just a summary of the parameters used for the report. This page also includes the TotalPageCount field;
- Page 2 uses 2 stored procs. The first one returns a dataset consisting of 1 row containing the headings for the columns of the data returned from stored proc 2. There will always be the same number of columns (only their heading will be different depending on the report), and the dataset is simply displayed as is.
- The data from stored proc 2 is also displayed on Page 2. The stored proc returns a matrix, always the same number of columns, which is displayed as is. All calculations, groupings, etc. are done on the SQL Server;
- Page 3 uses the third stored proc to display totals for the matrix from the previous page. This dataset too will always have the same number of columns, and all totaling is done on the database server. Just displaying the dataset as is.
That's it. All heavy processing is done on the server.
Because of the simplicity of the report I'm baffled as to why it would take so much more time when using the Viewer than from within the Designer.

Hm. Both options WERE selected, and deselecting them caused the report to run approx. 10 seconds slower (from the Designer)...

I've not done that (yet). Mainly because CR 10.5 came with VS2008, so it was easier to test to see if I can expect an improvement regarding my problem. Up till now, I see no improvement... ;-(

According to that list I'm using a correct version with VS2008. I might consider upgrading it to CR 12, but I'm not sure what I would gain with that. Because I can't exactly determine the cause of the performance problems I can't tell whether upgrading would resolve the issue.

The amount of network traffic is extremely minimal. Two datasets (sp 1 and 3) return only 1 row containing 13 columns. The sp 2 returns the same number of columns, and (in this clients case) a dataset of only 22 rows, mainly numeric data!
> u2022 The amount of time the database server takes to process the SQL query. Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports.
Ah. Here we get interesting details. I have been monitoring the queries fired using SQL Profiler and found that:
- ALL queries are executed twice!
- The 'data' query (sp 2) which takes the largest amount of time is even executed 3 times.
For example, this is what SQL profiler shows (not the actual trace, but edited for clarity):
Query                  Start time         Duration (ms)
sp 1 (headers)      11:39:31.283     13
sp 2 (data)            11:39:31.330     23953

> u2022 Where is the Record Selection evaluated? Ensure your Record Selection Formula can be translated to SQL, so that the data can be filter down to the server. If a selection formula can not be translated into the correct SQL, the data filtering will be done on the local client computer which in most cases will be much slower. One way to check if a formula function is being translated into a SQL is to look at u201CShow SQL Queryu201D in the CR designer (Database -> Show SQL Query). Many Crystal Reports formula functions cannot be translated into SQL because there may not be a standard SQL for it. For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated on the client computer. For more information on IF THEN ELSE statements see note number 1214385 in the notes database:

Not applicable in this case I'm afraid. All the report does is fetch the datasets from the various stored procs and display them; no additional processing is taking place. Also, no records are selected as this is done using the parameters which are passed on to the stored procs.
> u2022 Link tables on indexed fields whenever possible. While linking on non indexed fields is possible, it is not recommended.
Although the stored procs might not be optimal, that is beside the point here. The point is that performance of a report when run from the Designer is acceptable (roughly 30 seconds for this report) but when viewing the same report from the Viewer the performance drops dramatically, into the range of 'becoming unusable'.
The report has its dataconnection set at runtime, but it is set to the same values it had at design-time (hence the same DB server). I'm running this report connected to a stand-alone SQL Server which is a copy of the production server of my client, I'm the only user of that server, meaning there are no external disturbing factors I have to deal with. And still I'm experiencing the same problems my client has.
I really need this problem solved. So far, I've not found a single thing to blame for the bad performance, except maybe that queries are executed multiple times by the CrystalReports engine. If it didn't do that, the time required to show the report would drop by approx. 60%.

Remote Desktop To Windows Server Very Slow

I have OS X 10.6 running on a MBP and a problem that seems to be growing worse over time. I am using Remote Desktop (both CoRD and Microsoft Remote Desktop) to gain access to remote servers. One is a Windows Server 2008, the others are Windows Server 2003. Initially all was fine, but over the last 2 months access to the W2K server has crawled to a halt. Now, when accessing the other servers I'm having the same issue. I have tried different clients for remote access, used different high speed Internet connections (FIOS, a private network) and the result is the same. Very, very slow connections.
I have also tried using a different login on the laptop to no avail.
I booted Windows on my MBP using Parralels Desktop and tried using Windows RDC to the same servers; that works fine. In fact, I can access the servers very quickly using my iPhone's Remote Access software using the same Internet connection (home WiFi) as my MacBook Pro.
So I can only assume it's an issue with OS X 10.6, since different devices using the same Internet connection can make a much faster connection. But I can't find any similar posts on the issue.
Any ideas are appreciated!

Hi Jason,
From the error message, it seems that take time to load the user configuration properly from the server and then the network connection was slow. Please refer to following article

Boot up of Windows Server 2012 Essentials seems slow (extended Please Wait screen) and there are errors in Health Report

Dear Sir or Madam,
I have been experimenting with the evaluation version of WS2012e trying to get the installation and subsequent build into an optimal set up, and once I have everything I want it to do mapped out, I'll set it up with the full version with using the key that
I bought.
However, I've noticed that the server seems to experience a delay during cold boot - it sits with a Please Wait screen for about 60-90 seconds before it presents the screen with an option to Log on. I have also discovered from running Health
Report, that there are some entries in the event logs which appear to coincide with start up times, and which seem to be interconnected to each other in the issues they are describing, and I have copied an example of one of those health reports below.
I assume that everything sorts itself out in due course, because the events say the process will be re-attempted and these errors don't repeat again after the system has booted up. I also have the server set to suspend when not in use with the Lights
Out add in, so it shouldn't need to cold boot often - but I wondered if there's a way to correct these errors so that they don't hold up the boot up process? I'm also concerned that these errors will cause me later problems with storage pools and
the like at a later date - the disk replication one seems particularly worrying. Alternatively, are these errors just a normal part of the start up process - the timing of when different processes start relative to each other - and can be safely ignored?
In trying to understand what the events describe, I thought that WE2012e acted as its own Domain Controller, and yet it seems from the event log entries that it is waiting for another server to respond to AD / DC requests (but there isn't another server
on my home network). The other thing I remember from when I first tried out WS2012e, is that it took control of DHCP or DNS from the router, and I found that frustrating when waking up my laptop and it wouldn't connect to the internet until the server
had fully booted up and re-asserted its network settings. Is this another symptom of the same problem? I remember seeing a posting at the SBS Diva's site about how to update the server so that it gave connected PCs a backup option for connecting
to the internet when the server wasn't available, and was going to try to find that again to see if that helped.
By way of background - there isn't another server in my home network. This is an attempt to do a clean install onto the same hardware that I ran the initial trial of WS2012e, now that the trial has expired, so I'm not trying to migrate from an existing
server. I moved all the data on the trial server off onto an external disk, with the intention of importing it back once I had the Storage Pools set up the way I wanted on the new build, and since I didn't want to keep anything else about the server
trial. Am I correct in thinking that I don't need to go down the Migration route during installation, and can go through a Clean install in this circumstance?
I'm running on an Asus P8-H77-i motherboard, with an i5-3470s CPU and 16MB RAM, and I have WS2012e installed on 256Mb SSD formatted under GPT with uEFI boot - the latter being the main reason for the reinstall, instead of just giving the Evaluation
version the new key on the original MBR set up. I've also enabled Intel Rapid Storage and Rapid Start - and successfully set aside the hibernate partition on the SSD - but discovered that this is about forcing a hibernate after suspend, allowing
the system to power down until its needed again, and then resuming from hibernate on the SSD rather than cold boot each time. That seems to work, but doesn't improve the cold boot times at all, which was what I was hoping for - ideally the way my
laptop will boot from cold in a few seconds into Windows 8.
Yours faithfully,
Avon

The DFS Replication service failed to contact domain controller to access
configuration information. Replication is stopped. The service will try again
during the next configuration polling cycle, which will occur in 60 minutes.
This event can be caused by TCP/IP connectivity, firewall, Active Directory
Domain Services, or DNS issues.

The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS
data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet
Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

NTDS General
Event ID: 2147486534
The security of this directory server can be significantly enhanced by configuring the server to reject SASL (Negotiate,
Kerberos, NTLM, or Digest) LDAP binds that do not request signing (integrity verification) and LDAP simple binds that
are performed on a cleartext (non-SSL/TLS-encrypted) connection. Even if no clients are using such binds,
configuring the server to reject them will improve the security of this server.
Some clients may currently be relying on unsigned SASL binds or LDAP simple binds over a non-SSL/TLS connection,
and will stop working if this configuration change is made. To assist in identifying these clients, if such binds occur this
directory server will log a summary event once every 24 hours indicating how many such binds
occurred. You are encouraged to configure those clients to not use such binds. Once no such events are observed
for an extended period, it is recommended that you configure the server to reject such binds.
For more details and information on how to make this configuration change to the server, please see http://go.microsoft.com/fwlink/?LinkID=87923.
You can enable additional logging to log an event each time a client makes such a bind, including
information on which client made the bind. To do so, please raise the setting for the "LDAP Interface Events" event logging category
to level 2 or higher.

Hi KerguelanAvon,
Based on your description, it seems to be hard to narrow down the cause of this issue. Please refer to following operations and monitor the result. It may help us to go further, and then solve this issue.
1. Please refer to the following article and troubleshoot slow boot.
New Slow Logon, Slow Boot Troubleshooting Content
2. On your server 2012 essentials, please start a BPA scan and fix all that it can find, then monitor the result.
Regarding to those critical Errors in Health Report, please perform
Dcdiag on the server. Meanwhile, please refer to the following article and troubleshoot network connectivity, firewall setting and AD DS issue.
DFSR Event 1202 (DFS Replication)
Hope this helps.
Best regards,

Hi Justin,
I'm reading through the links you referred me to but it's taking a while. In the meantime I tried running BPA as you suggested. I'm sure when I ran it before, it didn't say much beyond 81 checks completed, and I couldn't find a way to get any
more detail.
Now it says
Problem:
The DNS client is not configured to point only to the internal IP address of the server.
Impact:
If the DNS client is not configured to point only to the internal IP address of the server, DNS name resolution can fail.
Resolution:
To resolve this problem:
1. From the client computer, open the Properties page for the network connection.
2. Make sure that DNS is configured to point only to the internal IP address of the server.
Except that it is.

I'll try rebooting from the current windows 7 build over to windows 8 on my dual boot laptop, to see if that makes any difference, since it is the only other client PC connected to the server at the moment.
Thanks, Avon.
