How to rename Windows 2003 server+Exchange 2003 SRV Netbios Name

We have two domains with the same netbios domain name and they can't create a
trust relationship between both.
How can I do to create this trust relationship? I should rename Netbios name
in one of the domains?? Or what can I do without depromocionate any of both?
Thanks

Hello Victor,

Domain rename operation is the only way to change NetBIOS name. But with
exchange it is more complex:

I agree with Danny and Meinolf. A domain rename is in order. The following
are some more info and links concerning domain renamesm especially if
Exchange is involved, in addition to what Danny and Meinolf posted.

================================================
Domain Rename Procedure and Notes:

Note: The Domain and Forest functional levels must be set to 2003. If you
have Exchange 2003, make sure it is minimal SP1 in order to support a domain
rename. If Exchange 2000, either upgrade to 2003, or Exmerge all of your
mailboxes to PSTs, uninstall Exchange 2000, run the domain rename operation,
then reinstall Exchange 2000, and use Exmerge to pump the mailboxes back in
the user's newly created mailbox accounts.

Also, if a PKI infrastructure was installed (Certificate Services), it will
need to be removed first prior to a domain rename:

The following was quoted from:
http://technet.microsoft.com/en-us/l.../cc738208.aspx

Keep in mind after a rename procedure, the DC's Primary DNS Suffix is not
automatically changed to match the new domain name. You are required to
change the Primary DNS Suffix to match the new name. In other words, unlike
the names of member computers, the DNS names of domain controllers in a
renamed domain will remain unchanged. The domain controllers can be renamed
in a separate step, using a special domain controller rename procedure,
after the domain rename operation is complete. You must double-check ALL
domain members to insure that their Primary DNS Suffix matches the new
domain name.

not match the name of the domain after you upgrade a Windows NT 4.0 primary
domain controller to Windows 2000
