         Windows updates - Error Code 80071A90 - Reverting back the updates

I came across a issue where the windows update getting installed and promting for a reboot and once i reboot every thing is gone.

During Startup, The computer is reverting back and updates are getting failed with an error code 80071A90.

Completly stucked and what to do now ? what is causing for this failures ? why the installed updates are failing during apply and why they are reverting back ?

All Quetions at a time, rebuilded the Windows updates database and tried many other ways, Still the issue is same.

Here is the resolution comes now :-) I started reviewing the release dates of pending update and noticed that there are few long pending udpates which are old.

Now started installing the 1 of the old update first, Wow its done.

Now second oldest update and done. Now i pushed few old and similar updates at a time and got installed.

Then pushed all the lastest updates and all got installaed successfully.

So what happen here is when installing all updates at a time, there might be combination issues between old and new updates and getting failed. Installting the older updates first and latest update later fixed the issue and computer is up-to-date

Spooler.Xml File - Huge Space

                       Spooler.Xml File - Huge Space in the directory %windir%\system32\spool folder.

you face this any time on Printer server, that Spooler.xml file is occupying huge space %windir%\system32\spool folder.

This is due to the Windows Error Reporting service for print spooler which has introduced from 2003 SP1. The majority of issues where seen in Windows 2008 server where print spooler is installed and if the Print Spooler  enters into a error state or crash or a busy condition the Windows Error Reporting starts writing the activity into Spooler.xml and keep on goes increasin its size. This log is like Extra level of logging for spooler.

This Windows Error Reporting  for spooler is enabled by Default, you can diable this feature by using the registry key.

• Click Start, click Run, type regedit, and then click OK.
• Expand the following subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
• Create a new DWORD Value, and then type DisableWERLogging in the New Value field.
• Right-click the DisableWERLogging registry entry, and then click Modify.
• In the Value data box, type 1, and then click OK.

Once the registry changes are made, please restart the print spooler service.

Done now we have stopped the logging of Spooler.xml file, go a head and delete the file to get the free space back on the server.

2008 R2- Remote Desktop Web Access (RD Web Access) for External Users

           Remote Desktop Web Access (RD Web Access) for External Internet Users

Today i went through an issue where remote desktop services configured for web access. We have a valid certificate and every thing seems to be fine.

We are able to access the RD Web APP both internally and externally, I can initiate RDP to the computers Internally and when it comes to External i am unable to initiate RDP, error " could not connect to the computer".

I have investigated on this and noticed that for External access of remote servers using RD web app we need to have any of the below condition.

• VPN Access: If are having the customers VPN connected then we can access the computers using RD Web app. 
• RD gateway server: The second option which is the very important option for easy RD web accessing of computer. We need to install the RD gate way service to the Remote Desktop Services role and need to configure this.

Few things to do after installing RD gateway: 

1. At "test.testing.com", log in as Administrator.
2. Launch "Internet Information Services (IIS) Manager".
3. Expand "test> Sites > Default Web Site > RDWeb > Pages".
4. In the detail pane, double-click "Application Settings".
5. Double-click "DefaultTSGateway".
6. Under "Value", type "test.testing.com".
7. Click "OK".

What happens if RD gate way role is installed and configured properly.

1. The users who are coming to access the network resource  (Remote computers etc.) they will be authenticating to RD gateway and from there it will be routing to the selected computer and establishes a session.
   
   
   Issue is resolved we are able to access the network computers out side the internet using RD Web Access App successfully. :-)

Lync Error - Active directory operation failed -You do not have appropriate permissions to perform this activity in active directory

Active Directory operation failed on lyncserver.lync.local, you cannot retry this operation "Insufficient access rights to perform the operations"

When i am enabling a domain administrator in the Lync control panel i am getting the following the following error:

-------------

Active Directory operation failed on “lyncserver.lync.local". You cannot retry this operation: “Insufficient access rights to perform the operation 00002098, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0″.
You do not have the appropriate permissions to perform this operation in Active Directory. One possible cause is that the Lync Server Control Panel and Remote Windows PowerShell cannot modify users who belong to protected security groups (for example, the Domain Admins group). To manage users in the Domain Admins group, use the Lync Server Management Shell and log on using a Domain Admins Account. There are other possible causes. For details, see Lync Server 2010 Help.

-------------

Solution:

• Open Active Directory users and computers snap in.
• Select advanced features from Veiw option.
• Now go to the user properties and security tab.
• Select advanced button and select check mark “Include Inheritable Permissions from this object’s parent".
• Come back to Lync control panel and start enabling user, it will get enabled successfully.

Lync Installation Error "The central management stores must match before the topology can be published"

Microsoft Lync error - The central management stores must match before the topology can be published - Can not Publish Topology because Central Management Store not matched

 

This was the Error i got when i am trying to publish the Lync topology.

What happen is first i tried lync installation in abc server and published it, durin this the configuration store location set at abc.lync.com\rtm.

No i have few issues with this abc server and started deployment on abc1 server and when i am trying to publish it i got the following error.

"The existing topology  identifies abc.lync.com\rtc as the central management store, but the topology that you are trying to publish indentifies abc1.stg.local\rtc as the central management store. The central management stores must match before the topology can be published."

 

Resolution step: 

The resolution is in two steps get the  Central management stores info and delete it using Lync shell.

• Initiated get-CsConfigurationStoreLocation which given me the below configuration store location.
  PS C:\Users\prakash.nimmala> get-CsConfigurationStoreLocation
  abc.lync.com\rtc
• Initiated remove-CsConfigurationStoreLocation to remove configuration store location from lync memory.
  PS C:\Users\prakash.nimmala> remove-CsConfigurationStoreLocation
  
  Remove existing configuration store location?
  Removing the configuration store location set to "abc.lync.com\rtc"
  will break your Lync Server deployment.  Do you want to continue?
  [Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help
  (default is "Y"):y
• Tried publishing the Lync topology again and i went successfull.

Active Directory Error: "The module "schmmgmt.dll" loaded but the call to DllRegisterServer failed with error code 0x80040201"

Active Directory Error: "The module "schmmgmt.dll" loaded but the call to DllRegisterServer failed with error code 0x80040201"

 

 Today i am trying to trasfer the FSMO role to one of my other test domain controller. All the roles trasfered successfully except Schema Master role.

When i am trying to register the Active Directory Schema Snap-in, i got the following error "The module "schmmgmt.dll" loaded but the call to DllRegisterServer failed with error code 0x80040201"

What is this error and why it is generated ??

This is not a critical error, it is due to User Account Control (UAC) limiting to initiate the command successfully.

We  need to run the command from an elevated command prompt to register the Snap-in successfully.

Here the User Account Control (UAC) might be limited our capability even we logged on using an account that is a member of the Schema Admins group. we need to login or start an elevated command prompt using an account that is a member of the Schema Admins group and the command completes successfully.

•     Stop and start the NTFRS Service.

•     Now go back to event viewer and keep an eye on FRS events.
  
  • when the recovery process start you will see event id: 13553
  • When the source server re-creates sysvol folder and it i will ready to accept the data from peer domain controller you will see evend id: 13554
  • Once the Sysvol is transfered and shared successfully you will see the event :13516.

• The issue will be resolved now, the sysvol will starts replication with out any issue.
