Moved to Server 2012 getting Access Database Corruption

We moved our company file shares to a new Windows 2012 server and are now having issues with Access databases becoming corrupted when accessed by multiple clients at the same time. Does anyone have any ideas on what could be causing this? We
were not having any issues with this on the 2008 or 2003 servers these were on previously.

We migrated from a Windows 2008 file server cluster with four nodes to a Windows 2012 R2 file cluster with two nodes.
After the migration to the new file server cluster our customers running Windows 7 SP1 started reporting Access Database corruption and slow file access.
However, if the SAME Access Database file was hosted on a Windows 2012 R2 file server NOT in a cluster there was no corruption.
I will not bore you with all the tests we ran while trying to determine the cause but here is what we did to fix the issue.
The solution was provided via an open case with Microsoft.
1. Create the following registry entries on all Windows 2012 R2 Servers in the new file server CLUSTER and reboot.
Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
Value: DisableLeasing
Type: DWORD
Data: 0x1

Windows Server 2012 - Direct Access clients and the Windows 8 firewall

Hi,
We're running a simple proof-of-concept for Server 2012 Direct Access, we have a single DA server behind a firewall using NAT. We have a number of client devices setup for DA and running Windows 8.
Our issue is that we can only get the Windows 8 direct access clients to connect (when outside the corporate network) and work with the windows firewall disabled (public network profile).
With the windows firewall disabled everything works exactly as expected. When outside the corporate network the client detects the network state (public network profile), connects via DA and all internal resources can be accessed successfully...fantastic.
Is there some specific guidance on manually configuring the windows 8 firewall for Direct Access ? We've tried the obvious TCP:443 with edge traversal enabled but without success.
Much of the information we have found relates to UAG rather than Windows 2012 DA.
Any assistance is appreciated.

Hi,
There isn’t any specific configuration on the firewall.
Just confirm that port 443 can be forwarded to DirectAccess server.
Of course, make sure you are using IPsec first.

Can DPM 2012 R2 backup SQL Server 2012 AlwaysOn enabled databases

Is it possible to use DPM 2012 R2 for backing up
SQL Server 2012 AlwaysOn enabled databases ?
Because if Alwayson configured for any Database , particular database is not available to select for backup.

Hi,
Yes, starting with DPM 2012 SP1 SQL AlwaysOn enabled databases can be protected as long as they are not part of sharepoint farm. DPM shows the Availability Groups under Cluster Group.
You must explicitly add the system account NTAuthority\System or NT AUTHORITY\DPMRA to the Sysadmin group on SQL Server.

Server 2012 Direct Access Single NIC cant get it to work

Hi,
I am having some real issues with setting up Direct Access with Server 2012 and a Windows 8 client, it simply won’t work at all.
First of all I should describe my setup:
I have an internet connection with a static IPv4 address on the external network adapter of the router
The internal network address (the address of the router which has the internet connection) is 192.168.1.1
Server1 (windows 2008 R2 Standard) has a static IPv4 address 192.168.1.2 and has some ports forwarded from the router (443, 25, 80) this server is a domain controller, email server, and has the DNS, DHCP and
certificate services
Server 2 (Windows 2008 R2 standard) has static IPv4 address 192.168.1.3 it has no ports forwarded from the router as it has no services accessed externally, it is used as a file server and print server, backup
domain controller and backup DNS.
Server 3 (Windows 2012) has static IPv4 address 192.168.1.4 and has the Remote Access server role installed along with all the other default features and roles it requires in the setup process.
These servers have all got an IPv6 address which I assume the server has configured automatically, there has been no deliberate configurations made to disable IPv6
I have no UAG or proxy server or anything else to route packets to internal servers. Just this router which has the option for port forwarding (I assume that’s NAT isn’t it?) sorry don’t know much about that
area.
I go through the setup wizard in remote access to configure direct access, in the external URL I have entered da.mydomain.com and created a host A record in my external domain name providers DNS which points
the da record to my external IP address. The wizard creates all the GPO’s, scoped correctly, and applied to a Windows 8 client. The operational status shows its all working and I got green ticks. However, when I connect the client to the internal network it
doesn’t seem to have correctly got the DA settings. I run the following in powershell
Get-DnsClientNrptPolicy
Nothing displays – at all
Get-NCSIPolicyConfiguration

I go into services.msc and find that the network connectivity assistant is not started, it wont start either something must trigger it but I have no idea how to get it triggered to start… this might be my only
source of problem perhaps but on a more network level question:
If I have such ports as 80, and 443 (which I assume DA uses in some form with a public IPv4 internet address) directed at server 1, how does the DA connection get to server 3 which has the DA role installed?
I could create another record on the server which also opens port 443 to server as well as for server 1, but then how would the router know which server to pass the DA connection to if the same port is open for two different servers?
Either way, this first issue is that the client doesn’t seem to have the ability to connect internally correctly yet, so maybe this connectivity service is a good place to start? My understanding is that the
networks icon in the system tray should show that there is a corporate connection, but it doesn’t. also, the client seems to have the NLS certificate in the computer certificate store, so the cert side of things is working and the GPO side is working.
Many thanks
Steve

ahh i see, so just to enlighten me even further...
If a company has two web servers that would mean they would need two different public facing IP addresses so they can route to each internal web server. If, like the big companies have, they
may have many web servers (possibly more than 100) I’m assuming that simply buying more public IP addresses would have a limit, especially since the IPv4 address space is pretty much exhausted. So is this where proxy systems come into play like ISA and Forefront,
is this what they do?
I assume if such a product was implemented you could go down to just one or two public IP addresses, point all traffic to the ISA server and that in turn would do all the routing of packets
to each server behind the NAT/router (probably based on some sort of domain name or sub domain namespace as it’s parameter for forwarding?)
Secondly, what I have done is installed windows server 2012 and used that as a direct access client (I read on another forum that the windows 8 RP doesn’t have the enterprise bits to make this
work). I have got much further with the 2012 server acting as a client (installed on laptop, installed desktop experience and wireless LAN),
but when I run the following command on my DA client I get the following status
Get-DAConnectionStatus
Status:
connectedlocally
Substatus:
none
This appears to work fine, when im connected to the local network. But then I disconnect and run the command again and I get the following:
Status:
Error
Substatus:
NameResolutionFailure
On my router what I did is temporarily disable port 443 going to my original server and instead opened it up pointing to my other server, so 443 traffic should be going to my DA server now, but I don’t understand why its giving the name resolution failure
status. I have a host A record called “da” with my domain hoster, and entered the full domain namespace in the DA wizard as da.mydomain.com (the Host A record has been up there for more than a week so it’s propagated through the net)
So, a bit further but stuck again.

Server 2012 R2 - "Access is denied." error

so this has been happening ever since i've installed Windows updates on our accounting server(windows server 2012 r2), and upgraded the RAM on the VM server(all these Server 2012 R2's are hosted on a VMware 5.5, client & server) . Sometimes, when trying
to log in as an Active Directory user via RDP, i'll get an "Access is denied" error. This occurs for 3 different users, all of whom are domain admins. When this done happen, I'm only able to log in as the local machine administrator. Our AD server
is also a 2012 R2.
Some things to note:
1) I can ping to the AD server, and ping from AD to the accounting server in question- all traffic is allowed over a VPN connection, and no traffic is being blocked by the firewall. Windows Firewall is turned off completely for both servers. Tracert finds
both servers in 3 hops, but times out on the 2nd hop. also, the preferred DNS server for the accounting is the IP address for the primary domain controller.
2) The time is the same on both the AD and accounting servers(at least when logged in as a local admin on the accounting server). Most of the most recent Windows updates are installed on both.
3) I've tried removing the accounting server from the domain, and adding it back to the domain, and removing the accounting computer object in AD- the computer object was never added back after rejoining the domain, automatically or manually.
3) I can't run a gpupdate on this accounting server. It returns this error:
Computer policy could not be updated successfully. The following errors were encountered:
Windows was unable to determine whether new Group Policy settings defined by a network administrator should be enforced for this user or computer because this computer's clock is not synchronized with the clock of one of the domain controllers for the domain. Because of this issue, this computer system may not be in compliance with the network administrator's requirements, and users of this system may not be able to use some functionality on the network. Windows will periodically attempt to retry this operation, and it is possible that either this system or the domain controller will correct the time settings without intervention by an administrator, so the problem will be corrected.
If this issue persists for more than an hour, checking the local system's clock settings to ensure they are accurate and are synchronized with the clocks on the network's domain controllers is one way to resolve this problem. A network administrator may be required to resolve the issue if correcting the local time settings does not address the problem. User Policy could not be updated successfully. The following errors were encountered:
The processing of Group Policy failed. Windows attempted to retrieve new Group Policy settings for this user or computer. Look in the details tab for error code and description.

Also, in the accounting server, i get multiple Microsoft-Windows-Security-Kerberos (codes 4 & 5)
and
Microsoft-Windows-GroupPolicy (codes 1030 & 1126) in the All
Servers > Events page. Where can i find the "Details" tab for the
error code and description?
any help would be greatly appreciated. thanks!

So I believe that I've fixed the time issue, but it still sometimes kicks off users on this accounting server, and gpupdate doesn't work. I have 2 domain controllers, and it seems that when this server queries the secondary domain controller(which was "screwed
up", i was told by the previous IT guy who set this environment up), i get the Event ID 1030[GroupPolicy (Microsoft-Windows-GroupPolicy)] error and error # 4(Security-Kerberos) after the gpupdate fails.
and Vivian, i do have a problem with AD replication. i cannot replicate the secondary DC with the primary DC. i get several event id 4 codes on the secondary DC.
when i try to force a replication via AD Sites & Services > Sites... Servers > NTDS Settings of primary DC > Right-click > Replicate Now, i get the error:
"The follow error occured during the attempt to contact the Domain Controller DCPRIMARYNAME(actual domain name hidden for privacy): The target principal name is incorrect."
which is interesting, because i've seen this "target principal name is incorrect" error in several event viewer error codes in different Servers(all 2012 R2).

Server 2012: Windows Internal Database error during installation

I am using the current RC build.
While trying to install IPAM services, I am prompted to install a Windows Internal Database.
However, setup consistently dies on me with an error that "The operation could not be completed, because the server that you specified requires a restart".
OK, fine. I restart the server and start setup again and I get the error again. Anyone seen this before?

Open up your domain group policy editor.
Navigate to the Default Domain Policy
Navigate to Policies -> Windows Settings -> Security Settings -> Local Policy -> User Rights Assignment
Find the “Log on as a service” policy and edit it.
Click on “Add user or group” button.
Add the following users: NETWORK, NETWORK SERVICE, SERVICE
Got to your Server 2012 machine and open an elevated command prompt.
Type in: gpupdate /force. Wait for it to successfully complete
Now try and install the WID .
You should now have successfully completed the installation.
This worked for me. I created a GPO for the container that the server was in, and applied the users as you showed. After a GPUPDATE /FORCE everything worked great, I was able to install the WID and then was able to install WSUS.
Thank you for this help and greetings from the US.

Directory Server 6.2 - Possible Database Corruption

We have become aware of a bug in Directory Server 6.2 only that could cause database corruption. We have a hotfix for this issue, and if you are running Directory Server 6.2 and run into this problem then you should contact Sun Support and ask for the fix for the following bug
6642430: DB corruption (zero’d pages) when performing db2ldif against large 20GB ldif file.
The sunsolve record for this bug can be found at [http://sunsolve.sun.com/search/document.do?assetkey=1-1-6642430-1].
NOTE: This issue does not affect Directory Server 6.0 or 6.1 release so you only need this fix if you are running Directory Server 6.2.
After you have the hotfix for this issue on Directory Server 6.2 and have applied the hotfix, then you will have to re-initialize the database from an LDIF backup to fully correct the corruption issue. Simply applying the hotfix will not fix the database if the database is already corrupted. Database corruption can be present though not detected with data in binary formats. You must therefore rebuild the database by importing an LDIF backup.
Directory Server Enterprise Edition 6.2 is no longer available for download and Directory Server Enterprise Edition 6.3, which includes a fix for this issue, will be available for download early April. When upgrading to Directory Server 6.3 from 6.2 (not needed if you are on 6.0 or 6.1), make sure you export the database (db2ldif) prior to the upgrade and then re-import the database after the upgrade to fully re-initialize the database and to ensure that no corruption issues remain.
Recommended patch or upgrade procedures:
<ol><li>     Shut down each directory server instance, as described in [Starting, Stopping, and Restarting a Directory Server Instance|http://docs.sun.com/app/docs/doc/820-2491/6ne3dhd8u?a=view#bcaan].
</li>
<li>     Perform an LDIF export of the database, as described in [Backing Up to LDIF|http://docs.sun.com/app/docs/doc/820-2491/6ne3dhdio?a=view#ganwh].
</li>
<li>     Install the [hotfix for bug 6642430|http://sunsolve.sun.com/search/document.do?assetkey=1-1-6642430-1] on Directory Server 6.2, or upgrade your Directory Server 6.2 instance to Directory Server 6.3 once Directory Server 6.3 is available for download (early April). You will need to login to Sunsolve in order to
     see this bug description.
</li>
<li>     Re-initialize the database from the LDIF exported in step 2, as described in [Importing Data From an LDIF File|http://docs.sun.com/app/docs/doc/820-2491/6ne3dhdj4?a=view#ganwc].
     If you are running replicated instances of Directory Server, make sure you read [Restoring Replicated Suffixes|http://docs.sun.com/app/docs/doc/820-2491/6ne3dhdjc?a=view#bcajf] as well.
</li>
</ol>

The entry was not imported most likely because it's parent isn't in the database yet. Are entries above this in another backend ? If so try importing that backend first. Also, that dn is so long, that it exhausted the buffer which is used to write messages in the access log. This is why, there's nothing after "which".
What is the exact reason why a export and import is necessary? Or is it only necessary if
the database is already corrupt? Is there a way to check that?The database corruption could be silent. So a binary backup/restore when going from 6.2 to 6.3 is not recommended and the LDIF route must be used.

Lost window, using published application on server 2012, when access it via web remote.

Hi,
We use an edi software installed on a Server 2012.
When we use this software accessing the server by Remote Desktop, everything works normal.
When we use the same software accessing the server by web access, (...softname/RDWeb/Feed/webfeed.aspx) where was published this soft application, we lost some windows after different actions.
For example if I do a modification for a value in one specific window, after I click save, that window disappear but can appear again only if I click again anywhere on my desktop.
In other words that window lost the focus and probably is still open under another window. Clicking again anywhere, will reactivate it and that window appear again.
Can you please help me to find a solution to this problem?
Thank You!

And I got public IP with 6 MBPS Dedicated Wireless line.
but problem is that my server getting huge speed uploading my ping goes high some time 3000 ms from other networks. some time request time out. when i same public IP assign in my personal Laptop there is no any issue every thing work good and fine.
and we are using SQL server one application which access from out side like this.
public It. 10.x.x.x./abcd.
when we access it it goes very slow and stuck .
so kindly give me best solution i will be thankful to you.

Hi Ashfaq,
I would suggest you to monitor the upload traffic via "Resource Monitor" in that server to find some clue .

Remote Event Viwer from Server 2012 R2 - Access Denied.

Dear Techpros,
Good Day,
I am having an issue while trying to view the event viewer of remote machines. Every remote snap-ins is working except the event viewer. I am using a Domain Administrator account and it is in the local admin group of the machine
Maybe there is a service to start or a local security policy to enable ?
I am stuck and cant find a solution to it. Grateful if you could help me find a solution to it.

Hi,
For this problem, it would be better to use Process Monitor to capture its process to find the reason of this problem.
Process Monitor:

In addition, have you tried to use other account to remote this system for test?

Access Database (.mdb) on Windows Server 2012 R2 Essentials

Hi guys, thanks for your time!
SCENARIO:
- Windows Server 2012 R2 Essentials
- Windows 7 Ultimate Clients (3 clients)
- VB6 application on clients using a MS Database (.mdb) hosted on the server.
- Clients access the database (.mdb) via a mapped network drive (K:).
PROBLEM:
- Microsoft Database (.mdb) on server gets corrupted frequently.
- Clients don't "flush their changes" back to the database: database was not updated.
WORKAROUND:
- Database was moved from the server to one of the Windows 7 clients.
- Application is running OK.
CONFIGURATION:
- Permissions are correct: network and NTFS.
- No faulty network hardware: switch, cabling, NICs.
- Computers and Server hardware is new.
- UPS are used everywhere.
SOME LINKS:
SMB 3.0
- Opportunistic Locking and Read Caching on Microsoft Windows Networks.
- Windows 7 cannot
open the shared MS Access database if it's opened by another user
- Initializing the
Microsoft Jet 4.0 Database Engine Driver
- Moved to
Server 2012 getting Access Database Corruption
Oplocks
- Configuring
opportunistic locking in Windows
- Understanding
offline files
- How to
enable and disable SMBv1, SMBv2, and SMBv3
- Is it possible to
monitor and log actual queries against an Access MDB?
Now, server is useless if it is not hosting our database. Any ideas, please? Do I need to diagnose using Wireshark? Or using Sysinternals Process Monitor? I think that is a waste of time.
Thank you!

Thanks for your reply.
Software is from a 3rd party provider. It currently supports concurrency. It was deployed on Windows XP. SQL Server would be a nice upgrade, however that is
not an option.
Something has changed with newer versions of Windows. That is what I am going to study in a lab I prepared with a real server and some clients.
File-sharing databases (Microsoft JET databases) are very old technology even before I was a college student. However, I have been very busy researching this technology.
It was made for multi-user environments. It is highly tied to file sharing services from Windows: SMB protocol.
Windows XP, Vista, 7 and 8 use different versions of this protocol. I think that is the root of the problem. With old technology, application was running fine.
With new technology, application is troublesome. I will check several things: JET drivers vs. ACE drivers, SMB tweaks, etc.
UPDATE:
Basically, there are 4 general answers to this issue:
1) Migrate your Access Database to SQL Server Express (or another RDBMS engine).
2) @Server: disable SMB 2.0/3.0 protocol stack by powershell command. Network speed decreases.
3) @Clients: disable client redirector caches by using regedit.
4) @Server: disable the leasing on the file server.
5) @Server: tuning Broadcom NIC parameters.

Getting Client Name in Remote Desktop Manager for Server 2012 R2

Remote Desktop Manager appears to have been replaced or moved in Server 2012 to Server Manager. It doesn't really matter to me where this is located, however I don't seem to have all of the features that were in Remote Desktop Manager (2008 R2). The biggest
one that I need is to be able to tell what computer each RDS user is logged in from. We use this quite often so we can remote into that users computer for troubleshooting.
Does anybody know how to obtain this information in Server 2012 R2? If it's not possible in Server Manager, can it be done with Powershell? A 3rd party application?
So far the only way I have been able to do this is if there is still a 2008 R2 server on the network. I can log into it and use Remote Desktop Manager to connect to the 2012 R2 server. Since a 2008 server can still obtain this information for a 2012 server
there must be a way to achieve this.
Thanks in advance!
Tom

Hi Tom,
In addition, the PSTerminalServices PowerShell Module might help.

You can run Get-TSSession in PowerShell.
Thanks.

How to make directaccess windows server 2012 access the IPv4 link

HI all,
I have built a directaccess for win7 with IPv4 only intrant successfully,and it work's good.but here is a problem that I can't access the IPv4 link,for example I can access

I do to make it works.

Hi,
Direct Access is an IPv6 technology. Clients send only IPv6 packets to DirectAccess server. We need an IPv6/IPv4 translator here.

Windows Store apps on Windows Server 2012 with XenApp?

We've got asked by a vendor whether our app will be able to support multiple simultaneous users, when installed on Windows Server 2012 and accessed via XenApp.
I suppose the real question here is whether or not Windows Store apps can be run in XenApp over Windows Server 2012 at all, and if so whether there are any special requirements on the apps to support multiple simultaneous instances execution.
The app itself takes each user through a log in procedure, during which all the dynamic user-specific data is retrieved from the back-end server; no such data is stored by the app locally.
Any advice will be greatly appreciated!
Thank you,
Alex
