OCS 2007 R2 Validation Error RRS feed

  • Question

  • I have recently implemented installed OCS 2007 R2 into a domain that had no OCS/LCS installations previously. All appears to work correct as users can log in on TCP and TLS and chat with each other ubt when I run a validation test on the front end server I receive errors regarding NTLM authentication as well as a failure to initiate a SIP conversation between the two users. The NTLM validation error is below:

    Attempting to login user using NTLM

    Maximum hops: 2

    Suggested Resolution: Use the maximum hop count to determine the server that generated this error. For example, if the maximum hop value is 2, then it is likely that this error was generated by a server that is 1 (immediate target) or 2 hops away. If the target server supplied and the home server for the user are different check the trust relationship between them. If the target server is an access edge server then check whether the internal supported domain list contains the domain of this user. In addition, check the forest-level domain supported list and make sure the user domain is present. Finally, run the dbanalyze tool on the home server to check whether the user is homed and configured correctly.
    Suggested Resolution: Check connectivity between servers. If this is an Edge Server, ensure that it is present in the forest-level Edge Server table.

    I have also run a debug session tracing the S4 and SIPSTACK protocols and it is showing alot of SIP/2.0 401 Unauthorized errors when trying to register to the OCS server, although there is no issue when using OC2007 on a workstation.

  • Hi Shayne,

    I ran into the same problem. Did you find a solution?

    Best regards

  • Hi hkillerm,

    Unfortunately no and as it did not appear to affect the functionality of OCS 2007 I ceased troubleshooting it. I had read some posts from people saying that having the test user accounts logged in via an actual OCS client while you do the test had helped them but it didn't assist me at all, maybe give it a try though seeing as it is simple.

    Sorry I can't be of much help.
