Well, as it turns out you are correct.

I've had VET anti virus running on the machine since day 1 without a 
problem, however it did an auto update and loaded a version onto the 
machine.  After checking the CA web site it appears that the latest 
version breaks stuff on machines with active directory for some 
unspecified reason.

I did a "downgrade" but it didn't fix anything, and then an uninstall - 
still no luck.  I can only assume that the downgrade doesn't actually 
uninstall the broken version but rather changes the running version.

So, I put back the broken version and uninstalled that hoping that it 
would properly clean itself out.  It did and SSPI is now working 
properly again and all is well with the world.

By the way, the sserver protocol was also broken but I didn't pick up on 
that until after I'd sent the email.

Thanks for your help,
