Hi,
i have had similar issues during this week. After looking for a solution everywhere i found out that i didn't set up the FQDN on this system.
Symptoms were:
- se38 > RSTPTEST timed out sometimes(not always)
- sm59 > TCP/IP connections > CALLTP_WindowsNT > test connections timed out sometimes (again, not always)
- STMS Overview > Systems: I was not always able to distribute and activate configuration from the Domain controller via Extras > Distribute and Activate Configuration (it died on the mentioned system)
- Transports failed mostly with the same error.
The error log was somewhere deep in ST11. It could not resolve our FQDN.
The solution, for me, was to add our FQDN to the WINDIR\System32\drivers\etc\hosts file.
We upgraded the kernel as well (from 7.20 patch 046 to most current) but this didn't help.
The FQDN is a concatenation of computer name and dns suffix of the network (if you have none, you can add one via rightclick on the used network adapter>ipv4>properties>Advanced>DNS tab, so in the end the host file looked like
127.0.0.1 localhost computer-name.ourSuffix.com
After this line has been added, the error stopped and the transports work again.
I hope it helps. Good luck.
