Exchenge 2010 server is not finding GC server in the domain even the domain controler . All Domain controllers are Windows Server 2012 Std. In the atest.local forest I have 3 DC and all 3 are GC:
PS C:\Users\administrator.atest> get-adforest atest.local ApplicationPartitions : {DC=ForestDnsZones,DC=atest,DC=local, DC=DomainDnsZones,DC=atest,DC=local, DC=DomainDnsZones,DC=cot,DC=atest,DC=local} CrossForestReferences : {} DomainNamingMaster : pdc2-v.atest.local Domains : {atest.local, cot.atest.local} ForestMode : Windows2003Forest GlobalCatalogs : {cot2-v.cot.atest.local, pdc2-v.atest.local, pdc3-v.atest.local} Name : atest.local PartitionsContainer : CN=Partitions,CN=Configuration,DC=atest,DC=local RootDomain : atest.local SchemaMaster : pdc2-v.atest.local Sites : {Default-First-Site-Name} SPNSuffixes : {} UPNSuffixes : {}
But on the Exchange 2010 side in the EventViewer I see the following message generated by ADTopology exchenge process:
Process STORE.EXE (PID=5740). Exchange Active Directory Provider has discovered the following servers with the following characteristics: (Server name | Roles | Enabled | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version) In-site: cot2-v.cot.atest.local CDG 1 7 7 1 0 1 1 7 1 pdc2-v.atest.local CD- 1 6 7 0 0 0 1 7 1 pdc3-v.atest.local CD- 1 6 7 0 0 0 1 7 1
which means that DCs pdc3-v.atest.local and pdc2-v.atest.local are not identified by ADTopology process as a GC. Why?
Thank you.
