It won't happen also because it will try and than generate an error (at least that's my experience when I tried it in a test environment as I'm always curious) EXAMPLE: Forest/Domain structure: Forest root domain: BLABLA.LOCAL Child domain 1 of forest root domain: CHILD1.BLABLA.LOCAL Child domain 2 of forest root domain: CHILD2.BLABLA.LOCAL Lets say all DCs in CHILD1.BLABLA.LOCAL are restored from backup. Because CHILD1.BLABLA.LOCAL went back in time all the GCs in the other domains MIGHT have newer data of CHILD1.BLABLA.LOCAL than the DCs in CHILD1.BLABLA.LOCAL. So all GCs in CHILD2.BLABLA.LOCAL and BLABLA.LOCAL should rebuild their data for CHILD1.BLABLA.LOCAL. On each GC in CHILD1.BLABLA.LOCAL and BLABLA.LOCAL (locally or remotely) execute: REPADMIN /UNHOST <FQDN GC that needs to rebuild CHILD1.BLABLA.LOCAL> DC=CHILD1,DC=BLABLA,DC=LOCAL Regards, Jorge -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Salandra, Justin A.

One other solution is to rebuild the child domain naming context on all GCs that are in other domains (I prefer the latter solution) (A few days ago I posted something concerning the GC contents when all DCs within a domain where restored from backup. Because all DCs are restored the domain went back in time while the GCs in the other domains contain current data. As the GCs with the newer data will never update the authoritative DCs the GC data concerning the child domain naming context has to be rebuild!!!) The tool to use for the latter solution is REPADMIN /UNHOST <FQDN TARGET GC> <DN NC> (w2k3 support tools) * If you are using cross-domain memberships check those to see if everything is OK * Finally check event viwer for errors and warnings and take appropriate measures * Don't forget to test/check trusts, computer accounts memberships and user accounts. Recreate accounts that were created after the backup that was used for the restore of the DC * Check ACLs on files and folders (SUBINACL) to remove unknown accounts These are a few steps you can use. Be sure to test these in a test environment!!!
