Few users are unable to sign in after we added 2 more front end servers in existing pool?
Hello, 

We have recently extended the Lync 2010 Enterprise pool with 2 Front end servers.  Now we have totally 6 Front end servers. 

After this change some users are unable to login. Error message: "Cannot loggin as server is temporarily unavailable"

Captured, client logs and received the following:

ms-diagnostics: 4004;reason="Credentials provided are not authorized to act as specified from URI";


We have the following security settings on the newly added front end servers:

Network security: Minimumsecurity for NTLM SSP Based clients - set to - Require 128-bit encryption 

In other existing front end servers, it has been set to - No minimum. 



Questions:

1. Is that the issue for signin failure?
2. Do we need to change this option to - No minimum in new servers and reboot it?


Please advise. MUCH THANKS.

Hi,

Those clients running in Windows XP or Vista OS?

If so check this:
