domain not available

Tue Feb 17 21:37:42 GMT 1998

hi mr dcm,

ok, there is a trick to getting a gdb attach to a process :-)

you have to first get the workstation to make the connection.  pressing
ctrl-alt-delete and going down to the domain box is sufficient (at least,
on the first time you join the domain) to generate a
"LsaEnumTrustedDomains".  thereafter, the workstation maintains an open
connection, and therefore there will be an smbd process running (assuming
that you haven't set a really short smbd idle timeout)

so, in between pressing ctrl alt delete, and actually typing in your
password, you can gdb attach and continue.

p.s mr dcm, what compiler are you using; what compile options (-O or -g -g
or none); what o/s; which NT (NT standalone server / NT wksta); which
version; (3.51; 3.5; 4.0); which service pack?

p.p.s to get any useful info in gdb, use -g -g.  this *may* make the
problem you are having disappear, if you aren't already using -g -g.
