I think it might have something to do with computer naming in the domain. If the computer has been rebuilt and renamed on the domain, will it try to send back some results as a different machine? I do see some errors in the event viewer. Errors are from Kerberos and DCOM. The kerberos error is as follows:
"The kerberos client received a KRB_AP_ERR_MODIFIED error from the server CLS-5RG4411$. The target name used was RPCSS/cls-ay1w071.cls.local. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (CLS.LOCAL), and the client realm. Please contact your system administrator."
The DCOM error is as follows:
"DCOM was unable to communicate with the computer 192.168.1.196 using any of the configured protocols."
However, when I run the test program from the server to this machine (cls-ay1w071, IP of 192.168.1.196) I get all OKs. The ones that fail use a target name of a computer that is no longer active on the domain.
Thanks
