I recently updated the schema on my domain to accept a windows 2008 server and installed exchange 2010 on the new 2008 server. I am now getting the following events on my domain controller that holds the Master Role. I'm not sure if I missed a step while doing this or what. (All servers except the new one are Windows 2003) Any assistance would be greatly appreciated.Here are the errors that I'm getting bfb-fileserver being the DC tha holds the master role : EVENT # 45080844 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 622 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 12:34:04 AM MESSAGE System Security Access Removed:Access Removed: SeBatchLogonRightAccount Modified: S-1-5-32-568Removed By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7) EVENT # 45080845 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 608 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 12:34:05 AM MESSAGE User Right Assigned:User Right: SeSecurityPrivilegeAssigned To: B1BANK\Exchange ServersAssigned By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7) EVENT # 45084701 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 622 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 2:20:40 AM MESSAGE System Security Access Removed:Access Removed: SeBatchLogonRightAccount Modified: S-1-5-32-568Removed By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7) EVENT # 45084703 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 608 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 2:20:40 AM MESSAGE User Right Assigned:User Right: SeSecurityPrivilegeAssigned To: B1BANK\Exchange ServersAssigned By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7) EVENT # 45088781 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 609 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 4:11:55 AM MESSAGE User Right Removed:User Right: SeSecurityPrivilegeRemoved From: B1BANK\Exchange ServersRemoved By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7) EVENT # 45088782 EVENT LOG Security EVENT TYPE Audit Success SOURCE Security CATEGORY Policy Change EVENT ID 621 USERNAME NT AUTHORITY\SYSTEM COMPUTERNAME BFB-FILESERVER DATE / TIME 3/16/2010 4:11:56 AM MESSAGE System Security Access Granted:Access Granted: SeBatchLogonRightAccount Modified: S-1-5-32-568Assigned By:User Name: BFB-FILESERVER$Domain: B1BANKLogon ID: (0x0,0x3E7)
