Only some computers have the following error:
Target computer name mismatch
I checked DNS and the records are correct and there are no duplicate / old records on any DNS server here. I can ping the affected PC by host name and it resolves correctly. I can VNC into the affected machines. I cannot UNC path to them. Windows returns the following error when using UNC path:
Windows cannot access - Error Code 0x80004005 Unspecified Error
However if I use the IP address instead of the host name then UNC path works. So I KNOW this is DNS related but all three DNS servers show the correct A records for these PCs. For whatever reason they are resolving to the wrong PCs even though when I ping them by host name they resolve correctly. The affected machines and my machine I am running PDQ on have all had nslookup ran on them and they all show that they are using the same DNS server, our second domain controller.
The Windows firewall is turned off. File and printer share is turned on. I cannot do remote management on the affected PCs. Access Denied. I am a domain admin. Most PCs in PDQ Inventory work fine. Only a handful have the access denied/name mismatch problem. When I click the More Info link and try a remote repair here is what happens:
Connect to IPC$ Share
Logon failure: Target account name is incorect
Access Admin$ Share
Logon failure: target account name is incorrect
If I directly sit at the affected PC and use the PDQ Analyze tool with the same credentials as always it shows that everything passes. What? When I run the analyze function from my computer, it fails.
Changing the computer's name allows access again. Changing it back to what it was denies access again. Even though the A records in DNS are correct those particular computer names can now never be used again as they are somehow tied to IP addresses that DNS isn't showing. What would be responsible for this? This physical location where the affected computers are at has recently been given it's own DNS and DHCP and Domain Controller. The DNS records on that DNS are correct however and not every PC over there has this issue. Most are fine. There has to be some issue with the DNS server or maybe something wrong with the DHCP but I'm not the one that set those up so I'm not sure. What would cause this?
