Samba regected as WINS server on local workgroup.

[gexcko]

I've set up samba on ubuntu 8.04 server as a local & domain master browser serving WINS to my subnet. It appears to work fine for a while, until one of the pcs (almost always running Win XP Pro) rejects it. Shortly afterward I'll start seeing errors about __MSBROWSE_ missing (I have no idea what this means) and none of the other computers on the network (Win, Mac, or Linux) can browse the workgroup, although they can directly connect to shares on the server or any other computer.

Note that the PC at 10.10.10.192 rejecting the server is a XP Pro.

Any ideas on a starting point to troubleshoot this would be great.

I should also point out it's not always the same PC that rejects the server as local master browser.

One option might be to boost the "oslevel" of the server.

I had the os level at 35 -- I'll try bumping it up to 65 and see if it reappears. Isn't samba supposed to by default win elections over any windows box expect for nt server 2000+?
