Windows Registry information changed after domain change ??

[fniles]

On this one Win2000 Server, we changed the IP address, default gateway,
preferred DNS and the domain. After we did that, we could not run this VB
application that has been running fine before the changes. It was missing
DLLs and some Windows Registry entries (in HKEY_CURRENT_USER) are missing.
We login using the same administrator user.

When you change a machine's IP address, default gateway, preferred DNS and
the domain, do the information in Windows Registry in HKEY_CURRENT_USER
suppose to change also ? Thank you.

If you changed Windows domain membership, you got a
completely new set of domain users. These users have
different security IDs, whether or not their text names are the same.

Windows creates a new profile folder for this new "SID." Your old
user registry is in a different folder that is connected to
the old domain account. (If you rejoined the old domain your
profile will map back to that.)

You want to copy your old profile folder over the new profile.
You can see the profile folders in c:\documents and settings,
and you can copy them using User Profile Management in
my-computer properties, or using xcopy. Alternative you
can use a roaming profile seeded with the old profile
folder also. Be sure to backup before deleting or overwriting
anything in the profiles.

Do I need to copy the old profile folder before or after I change the domain
?

How about DLLs ? After we changed the domain, we could not run the VB
application that has been running fine before the changes. Besides missing
some Windows Registry entries, it was also missing DLLs.

Thanks.

DLLs normally are system-common, both in the registry and
on the system disk. If the DLL files are not in the user profile tree
there is no reason they should be missing just from a domain
switch.

They may have NTFS file protections set so that you can't use
them from the new user ID - you'd have to do a search as administrator
to see if the DLL files are there, and what protections they have.

It is possible to register DLL classes in the user portion of
the registry - though this is very rarely done. If your application does
that, then restoring the user registry should fix it also.
