Reset Sign-In address in Communicator (automatic vs manual configuration)

Why would you need to reset the Sign-In address in Communicator?

Communicator automatically queries the AD for the correct Sign-In address when logging into communicator (if logged into the domain)

In case for some reason users have changed the Sign-In Address manually, Communicator does not query AD at startup.

If you want to reset this manual overridden behavior then you need to delete the following registry key.

If you want to do this for example in a login script then you can use this command line: Reg delete HKCU\Software\Microsoft\Shared\Ucclient /f

The next time Communicator starts up it will query AD again for the correct Sign-In Address for the current logged in user

Thanks to Marc J for pointing this out.

Hi,

Great post. Do you know how communicator queries the AD for the correct sign-in address on 1st login? as you described above?

I have LYNC 2010 setup and in Domain A and when I login communicator automatically logs in for all new users - which is what I want.

I setup a trust with Domain B and when new users login communicator is unable to query AD to obtain the users sign-in. However, if I manually enter the SIP it can login and works for all subsequent logins.

As you can see I have LYNC 2010 installed in a Resource Forest and my Users are in a Accounts forest.

Do you know how to enable Communicator to query the AD to find the users SIP login on 1st logon for users from a different domain? Basically, I want to set up so when new users login to Domain B communicator is able to automatically query AD for the correct signin name and auto log them on. (as mentioned before this works for users in Resource Domain A where LYNC 2010 is installed but does not work for users in User Domain B).

Sorry for the long comment and hope I make sence

Thanks in Advance
