Clients cant connect to WSUS server after WSUS re-install

Hi,
I have a 2008 R2 WSUS server that was working and patching fine. I uninstalled and reinstalled WSUS as I wanted to clean up the considerable amount of old update files. I inherited the WSUS job and this server was just a bit too messy so I thought a fresh
WSUS would be less time consuming.
After the reinstall though no clients report to the server anymore. I can ping the server, and hit it via IE. If I try update a client I get the common error 80072EFD. I have the latest log from WindowsUpdate.log

I have a 2008 R2 WSUS server that was working and patching fine. I uninstalled and reinstalled WSUS as I wanted to clean up the considerable amount of old update files.
After you reinstalled WSUS did you also reinstall the required patch.. to wit, in this case, KB2938066?
While Don is correct about the port, in this case, it's not a port mismatch causing the problem. Attempting to communicate with a valid WSUS server on port 8530 that is actually installed on port 80 would return an HTTP 404 error on the selfupdate task.
Likewise a failed installation to port 8530 with missing selfupdate resources would also return an HTTP 404.
This is a CANNOT_CONNECT error: 0x80072EFD, indicating that either the client has the wrong hostname, the IPAddress has changed (and DNS not updated) -- neither of which are likely for a simple reinstall of WSUS -- or some other network issue is interfering
with the client's ability to communicate with the WSUS server... NONE of which should be of consideration when doing a simple reinstallation of WSUS.
So, either more than just a simple reinstallation of WSUS happened, or something else also occurred in the network concurrently.

Mac OS 8.6 Auto network connect to a server after reboot is not working

We have multiple old blue and white systems on a network. All but one will automatically connect to the network when rebooted. I have gone into Chooser, Appletalk, put in the server IP address, put in the server password, checked the boxes that say remember Server name and password for next startup. I can connect at that time with no problem. When I reboot, the server does not automatically hook up. I have to go back into Chooser, etc. I created an alias on the desktop, but it still prompts me for a password to connect. I have performed a clean install of the Mac OS 8.6. It still does not connect to the server after reboot (after configuring all the settings again after the clean install). Please help..

Can I find out how many clients are connected to a server process?

Hi, I am hoping I can find out how many clients are connected to a server process. This could be either a programmatic lookout number, a number in a log file etc.
By the way, does lookout have any application (not data) logs? I have noticed that occasionally lookout will crash and I cannot find any logs to determine why, what processes were running, who last accessed it etc.
Thanks

Hello,
There's currently no way to acquire this data. I think that'd be a great suggestion for the product. Please submit your feedback to our developers at the following link: http://digital.ni.com/applications/psc.nsf/default?OpenForm&temp1=&node=

I suggest you try the very clean and very forceful AutoLoader method:
http://supportforums.blackberry.com/t5/BlackBerry-10-OS-Device-Software/Upgrading-OS10-devices-using...
Beware that it is completely destructive...the device will be "like new"...no data, no apps, no accounts, etc. Be sure you take a full backup first, as well as make full manual documentation of all apps, accounts, configurations, etc. Sometimes a restore reintroduces the very corruption one is trying to eliminate, and manual reconfiguration is necessary.
You can also use this to fall back to a prior OS if you desire...you can install any OS level for which you can find an AutoLoader. (Hint...search over on the CB site!)
Good luck and let us know!

When i plug my phone into itunes for the ios update, it downloads but then says it cant connect to the server. How do i get my update?

Here are Apple Steps for Error 21:
This error typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
My additional advice:
Also Error 21 can occur with DFU Mode Restore, try Recovery Mode Restore. Restart computer. Open iTunes on computer. Connect iPhone to computer. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode. This usually takes about 20 seconds of holding both buttons. Click Restore button of iTunes.

TS3276 iCloud email on OSX 10.8 does not connect to the server after sleep

iCloud email on OSX 10.8 does not connect to the server after sleep. The only way I can reconnect the iCloud email is to restart the computer. Does anyone have any ideas how to resolve this issue?

I would suggest you try opening "Mail">click on "Mailboxes" in the Menu Bar> and select "Rebuild" from the list. That may solve it.

Win7 clients can't connect to OSX Server after 10.10.2 and Server 4.0.3 update

I'm troubleshooting an annoying issue with our Yosemite fileserver at work and hoping someone has suggestions.
The server is running Yosemite, clients a mix of MacOS from 10.6 through 10.10, and some Windows 7 boxes.
With the server on 10.10.1 and the just-prior version of Server (4.0, I assume; were 4.0.1 and 4.0.2 ever available to the public?), everything basically worked. Last night, I updated the server to 10.10.2 and 4.0.3. Nothing unusual during the update apart from a bunch of spotlight indexing processes running as individual users sucking up a lot of CPU for the first few minutes, which may be normal.
However, now almost all the Macs are fine, but the Windows clients are all getting permissions errors when trying to connect. Even weirder, one Yosemite client was also getting an error on login when trying to connect via SMB, both on 10.10.1 and 10.10.2; the same computer connecting via AFP works fine.
I'm inclined to think that it has something to do with the switch to SMB3 mentioned in the changelog for Server 4.0.3, although I'm not 100% sure that didn't exist under 4.0 as well, and if this is the problem I'm not sure what to try to fix it.
I'm already aware of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel needing to be at least 3 (or non-existent, so it defaults to 3 on Win7) to work with Yosemite; these clients already have that registry key set. Suggestions?

Addendum: I just realized that the Windows users *can* see their own home folder when they connect to the server without the main share I'm trying to mount specified. So it's not that they're completely unable to connect, it's just that the server isn't offering them any of the main share when they do.
When I tried mounting the server from 10.6 manually forcing SMB (with an admin user, no less), I got the same thing--just my user folder, none of the main shared volumes...

Essbase Administration Services: Cant connect to Administration Server

Cant connet to Administration Server via EAS console. I would appreciate any hints that might help me overcome this next unknown.
Background follows:
I installed EPMA 11.1.2.2, and then went to the workspace wondering where the sample data was (after I created a sample app). I discovered in docs and forumns that I had to load it through the Essbase Administration Services console. Now I'm trying to get that to work. I installed it after posts revealed that it is part of the client installers (thanks John) package. Now that it is installed I run it, try to login, and get an error message that says "could not connect to Administration Server." I reinstalled the EAS database as a new install to my server.mydomainb.org:1433 via the configurator. Then I redployed all the apps to the app server. And lastly started all of the services. Still I get the same message. I've done this about 4 times hoping that a reconfig will somehow fix something but still no joy. I've also tried loggin in with different names for the server such as myserver:1433 or myserver.mydomain.org:1433 or myserver and none of those helped either.
I have manually started all the services so they appear to be working. I may be missing one but I wouldn't know.
The services that are running include:
Hyperion EPM Server - Web Application
Hyperion EPMA Server
Hyperion Financial Data Quality Management
Hyperion Integration Services
Hyperion Reporting and Analysis Framework
Hyperion Studion Services BPMS bpms1
Some in posts have suggested also going to the logs. 11.1.2.2 docs say that the EAS logs are located at oracle_home\user_projects\domains\epmsystem\servers\EssAdm..Services0\logs\easserver.log. But I found mine at:
<oracle_home>\user_projects\domains\epmsystem1\servers\logs. You will notice that my empsystem is empsystem1 instead. There I found that the easserver.log file is empty but I did find one error in the file EPMServer0.log. The error I found is as follows:
####<Apr 4, 2013 11:42:09 AM MDT> <Error> <JDBC> <SLCBRASSTEST> <EPMServer0> <[ACTIVE] ExecuteThread: '18' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1365097329966> <BEA-001112> <Test "select count(*) from SERVERLOGID" set up for pool "eas_datasource" failed with exception: "java.sql.SQLSyntaxErrorException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Invalid object name 'SERVERLOGID'.".>
I'm not sure what to try next so any suggestions would be helpful. Thanks!

"Hyperion EPM Server - Web Application" indicates that the web apps have been deployed to a single managed server, this means the web apps will be running a default port of 9000, the EAS console is not aware of the port so you will need to include it when you add the server in the console e.g. servername:9000

8.8 Client cannot connect to Windows Server 2008 error -1102

SAP Business On 8.8 on PL 18
This is not the first time I have had this issue with Windows Server 2008.
however everytime the resolution was diffrent. Now this site is causing trouble.
The issue is the client cannot connect. We have the log on window, can see the company list. type on the password and we get a -1102 error.
The client on the Server itself can log on. It is the cleints that cannot.
I checked these below.
1 SQL Native client is installed and ok.
2. Licence server is configured and ok
3. The user has admin access to locl PC
4. The SAP user name and password are correct ( client on server can connect fine )
5. The ports 1433, 30000 and 30001 are open on the server.
6. Through SQL server configuration the named pipes and TCP are enabled.
7. SQL server browser is running
The only things I have not tried are
The Firewall is running on the server and I have not yet stopped it. Will try that tomorrow.
Do you have any other ideas please ?

I have got this working but I am not confidant of the outcome - yet - I really need your expert advise here.
This is what I did. In that order.
1.     As Owen suggested I checked if there was a specified Port for the instance. What I found was TCP Dynamic ports were enabled ( SQL server config manager | network configuration | tcp properties ) and there was no TCP port specified. Assuming ( ai may be wrong) that the system assigns a dynamic port to this instance I set it up so the Dynamic port does not happen and manually specified the Port 1433. Restarted the SQL Service. ( still having the Port 1433 open in the firewall). This did not solve the issue.
2.     With the above setting still on, switched off the firewall. Went to the PC client and SAP can log on now. Now keeping the SAP client running, switched on the Firewall on the server. Log off SAP on PC client and log back in ( with firewall off ). SAP now can log on.
3.     I had to do the above step for all PCs to get them working.
4. Currently the firewall is on and clients can connect
So what could be happening? I have no clue. It is apparent there is some setting that gets saved within the PCs ( may be user profile) after the first log on with the Firewall off - to say its safe ?
However I have no idea what will happen if the server is restarted u2013 this server we cannot restart any time we want as itu2019s a critical server and runs other things.
I would still like to get to the bottom of this to understand what is happening.
I have a SAP message running too and will ask them this same question.

Lync client cannot connect to Exchange Server when accessing from outside (Internet) - please HELP!

Hello,

Call Logs, Voicemail and Calendar information.
Here is the experience and error messages that anyone will see when connecting to Lync server from Outside:
And this is the error message that will be displayed on Lync phone edition devices (a.g. Polycom CX-700) when connected from Internet:
If somebody can suggest what I can try I would appreciate this very much. I do believe that many other people have this issue as well.
Thanks!

Hi, we had this issue and I ended up logging a MS support job. Turns out it was the TMG rule/Auth method causing the issue.
Job details:
**Symptom:
Lync Client External User are not able to retrieve the EWS URL
**Troubleshooting:
• We found External users are not able to Retrieve the EWS information in the Lync Client .
• We found the below error in the ETL logs.We found for EWS request we are getting the 401 response
HTTP/1.1 401 Unauthorized ( The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator. )
• TMG need pass through Authentication
Public names are autodiscover.domain.com and Outlook anywhere External FQDN and paths are /ews/* and /autodiscover/*, OAB/*
Users is All Users, and Delegation is "No delegation but client may authenticate directly" on the corresponding tabs of the publishing rule.
This changes is required for Lync Client as Lync Client does not work well with this BASIC authentication on TMG .
• After TMG engineer changed this settings in the TMG users are able to see EWS information.

External Clients cannot connect to Exchange Server

Hello all:
My external clients using outlook cannot connect to Exchange Server 2013. We have on-presmise version updated to Cu3 and after the Cu3 update we lost connectivity with Outlook clients. Many of the settings in IIS were changed after the Cu3 update,
I noticed after my http->https redirect was not applied anymore to the default website. Here is my Get-OutlookAnywhere results:

Thanks in advance

Hi,
According to your description, users cannot connect to Exchange server 2013 both internal and external.
Please run Test E-mail AutoConfiguration in Outlook to check your autodiscover service. Also
reset your Exchange virtual directory to connect correctly. If the issue still continues after all configurations are setting properly, collect some Event logs would be helpful.
If there is any question, please post the results here for further analysis.
Thanks,

Safari cant connect to a server.

I have Safari Version 7.0.2 (9537.74.9) Running on a powerbook with   10.9.2
message. when I open google, facebook or twitter... "Safari cant connect to server."
and firefox .. but I can open almost any other website.
This is the message I get in Firefox.
Unable to connect
Firefox can't establish a connection to the server at www.google.com.
    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Sometimes when I restart the computer it works for a few minutes then it gets blocked again...
I have tried restarding the browsers, deleting the cookies and a few other stuff but nothing seems to be working..
This is a new Mac ANd I havent installed many programms in it.

You, or someone using your computer, changed the network settings in an attempt to bypass copyright restrictions on Netflix. The illegal DNS server you're using should never have been trusted and now doesn't work.
Delete all the DNS servers by selecting them and clicking the minus-sign button at the bottom of the list. You may have to unlock the settings first by clicking the padlock icon in the lower left corner of the preference pane and entering your administrator login password when prompted.
If the server addresses are grayed out and can't be deleted, even with the preference pane unlocked, then the change was made on your router. Refer to its documentation to find out how to reverse the change. The router should get its DNS settings automatically from the ISP.
Click OK, then Apply. The DNS server list should be repopulated automatically with the address of your router, or the addresses of the DNS servers provided by your ISP. If that doesn't happen, open the TCP/IP tab of the preferences and click Renew DHCP Lease. If you're not using DHCP, manually enter the DNS server addresses you got from your ISP, or else use these temporarily:
8.8.8.8
8.8.4.4
