You can enable client specific logging and see if it turns up anything.


Access a share and review the logs.

Is this Windows 7 workstation accessing the new member server and

Can you run on both member servers and report?

testparm -v |grep "client ipc max protocol" and testparm -v |grep 
"client ipc min protocol"
