Greetings

We have been running ServiceDesk plus for a number of years but have run into some issues following a DC upgrade to Server 2012R2. We keep getting NTLMv2 authentication pop-ups when accessing the SD+.

We have a mixed environment and so our Lan Manager security settings are set to LM & NTLM with NTLMv2 if negotiated. We have been attempting to troubleshoot this issue with Manage Engine with no luck, excerpts from some of the most pertinent logs below if anyone has any ideas.

sso log:  

HttpSecurityService: Failed to connect: 0.0.0.0<00>/ DCIP

jcifs.smb.SmbException: Failed to connect: 0.0.0.0<00>/ DCIP 

jcifs.util.transport.TransportException: Connection in error

Network Monitor:

Http: Request, GET /ntlmv2 

Http: Response, HTTP/1.1, Status: Unauthorized, URL: /ntlmv2 , Using NTLM Authentication

Http: Request, GET /HomePage.do, Query:logoutSkipNV2Filter=true

It will allow us into the Service Desk in most cases but the NTLM pop up is causing us complaints. Any useful help would be appreciated.
