Thanks.

I took a chance with one of the test servers and removed
it from the domain by putting it in a workgroup, rebooting
it and then rejoining the domain followed by another
reboot. Thankfully this worked & the machine is now
visible to the domain again. I've tried this on one of the
SQL servers & it's fixed that as well.

For the moment the problem is sorted but I am still
concerned over how/why it occurred in the first place.

Mike.
