That error is coming from the server.

I would definitely try to upgrade to the latest. It's more stable than
1.2. I know it's a pain to QA but it does provide more robust handling
for the filter. Look at the release notes for specific changes. Some
are detailed quite a bit.

I can't guarantee it will fix your problem though. The client interrogates
the DC with a tree connect to IPC$ when it first connects but if the
NOT_ENOUGH_MEMORY error occurs after that you will still get an error. It
should close the connection though causing a new one to be established
which appears to be working in your case.

I think you should try the latest with the default config.
