XP & Copiers not connecting to Server 2012

Any chance there were new MS updates waiting for the system restart to complete their installation?  If so, check the installed updates to ensure nothing might be related to the issues.

Is your crashed Server a DC? If so, make sure to do a full power down and then a cold boot to verify authentication to the DC is working. What is sounds like is that nothing is authenticating properly.

Scans fail - can't authenticate
Can't log on to PCs - can't authenticate
Cannot connect to the Domain - authentication issues

Pinging the Server IP is good I assume? Are mapped drives working?

Please give more info on how you were able to get things working on the loaner PCs. Are they Domain computers or on a separate workgroup? This will help us to identify whether it is connectivity or authentication related. Can you ping the IP of the Server from the problem PCs?

loaner pc was a windows 7 pro.. connected to the domain just fine.
all other pcs on the network, all windows 7 are working properly, connecting to server resources without issue

connectivity across the board is working great. ping server name and domain name without issue.

server didn't crash, it was a planned reboot. they lost electric and a pc connected to a database lost connection locked a record. server and all backend network equipment on ups power and protection...

Did you check DHCP and DNS to make sure there aren't any conflicting records. WIN7 resolves conflicts better than XP.

I would do a ipconfig /flushdns on the server and XP and test.

no updates run recently

flush of dns did not help unfortunelately

Remove all affected pcs from the domain and then re-add them. The profiles for Users will not be affected.

did that with the xp system.. removed from the domain.. added to a workgroup, tried to re add to the domain.. wouldn't go in..

If it wont join the domain, what is the message exactly? You will receiblve a message upon failure. You may want to retry joining the Domain using DomainName.local . Sometimes the local is required.

when it was connected to the domain when accessing network resources we would get the specified network name is no longer available. connectivity was solid, name resolution was solid for the server name and the domain name

trying to connect it to the domain after the fact, I'm sorry but I don't have that message any longer. we would try general name abc, as well as abc.local when trying to join. both produced the login to domain prompt, but both would eventually fail.

did you rename the computers something different or use the old names. The SID is likely the problem if you used the same name. Remove the computers from the domain again delete the computer names from Active Directory and add back. Or rename the computers before adding back to the domain.

yep tried that as well. changed the pc name.. removed the old from ad.. even added the new one in ad.. still didn't work..

again, issue not localized to xp, copiers that scan to the server are also affected. they use smb protocol..

Not sure I would mix troubleshooting with copiers and workstations? What happens when you manually place the DNS server IP in the workstation NIC and try to connect to the domain?

Once the workstations are back online worry about the copier. may even add the DNS setting on the NIC of the copier as well.

on the workstation we set it to static from dynamic, didn't resolve the issue.

not mixing, but they were experienced at the same time, so can't ignore that fact of it.. and the possibility that it has nothing to do with the workstation itself and maybe something related to how both types of devices communicate with the server.

then you have a DNS problem or DHCP

regarding a copier and workstation yes they are on the same network but they are two completely different pieces of equipment. It's more likely the copier will work after you repair the workstation then the other way around.

turn off the firewall on the PC

what does nslookup tell you on the XP machine

other suggested options did not resolve the issue
