I've read through what seems like hundreds of formum entries and Google search articles, but have yet to locate a situation similar to mine.
SCENARIO:
Our hardware team recently delivered a newly imaged windows 7 64 bit PC to a client. With exception the Lync 2010 client, all else appears to function correctly. Lync immediately kicks back the 'Cannot Sign in because server is temporarily unavailable.'
message regardless if we use Auto sign in or attempt manually using the FQDN or IP address.No one can sign into Lync on this particular PC. Aside from this PC, we have no other reported cases of sign in issues. We only allow connection to Lync on our internal network or through a VPN connection to our internal network. Also, we only
use IM and Presence. All other options are disabled.
ATTEMPTED FIXES:
- Auto sign in, Manual Sign in (FQDN and IP address)
- Uninstalled and re-installed Lync 2010 client.
- Forced update of Root certificates.
- Deleted and re-imported our CA Server Certificate.
- Turned on both Logging check boxes in Lync Options. (Don't get anything that seems relevant in Event logs. Unable to view .etl files, since we currently don't have the proper tools installed on Lync Server.) I was able to review the UCCAPILOG File, but I'm not sure how to interpret the results.
I would appreciate any feedback as I want to get this issue resolved and assure there isn't something wrong with the way our team is imaging new PCs to prevent further issues.
