Observing spikes in "AD Search Subops" counter and "PROC LSASS%" counter daily on DC A relative to DC B; its not in maintainence windows; its at start of business hrs daily.
-> Eliminated the point of hardcoding because, one time for brief moment of time DC A went down and there was spike in DC B, which means the connections know how to go to a different DC but are choosing not to. -> My question is, can it be something wrong with link-cost stuff(unlikely since both DC's are in same site), is there some setting which makes LDAP connections go to 1 DC in rather than taking random approach? -> Both DC's are 2008 R2's.
Appolozize if details are few, please ask me if anything required.
