Samba server periodically missing from Network Neighbourhood

[Gerry Kirk]

Using 2.0.7

Yesterday, I removed our NT server and switched over to Samba as a PDC. 
It's been mostly a smooth transition, but I have noticed two things:

1. The Samba server periodically disappears from the list in Network 
Neighbourhood. I'll refresh the list and watch it pop in and out.
2. The logon script is not always executed. I wonder if this is related to 
the first problem.

Has anyone else experienced this?

Thanks,
Gerry
