Hi,

We have a major issue with our current network with our local users' computers hostname change by itself.  The explaination is listed below.

We used "Quest" migration tool to migrate our AD to the new domain, however, it was not successfully.  We still have our old domain and shortly after this, we are logging back into our workstations and seems the host name pinpoint to,i.e, 1000-XP, which is one of our user's computer hostname.  That particular computer is online, but the other computers getting the same hostname.

It seems the other computers are affecting by some sort of corruption in our AD.  The NETBOIS Name shows the correct original hostname in the System Properties, but the Computer Name and Full Computer Name was change to 1000-XP. Some instant, our static IP was also changed.

We have scanned our network with virus/spyware, but did not catch anything.  My only pin point was Quest somehow mess up our AD.  Any other suggestions or hints would be very apprectated.

What name do you see from a prompt:

echo %computername%

Does it show the correct name? If yes then it's likely the DNS servers and DHCP server on your original AD or on the new AD is misconfigured.

Thank you for the suggestion.  The echo %computername% came back as the correct hostname, however.  I will look further into the DNS and DHCP setup.  Anyone have detail DNS & DHCP, I would be appreciated.

Most DNS problems are VERY easily troubleshot and identifiable if you can follow the steps a DNS query takes. I would like to share the step-by-step a DNS query takes from the origin to the destination. _____________________________________________…
Configuring network clients can be a chore, especially if there are a large number of them or a lot of itinerant users.  DHCP dynamically manages this process, much to the relief of users and administrators alike!
