The operation took longer than expected.

[Jason2005]

I have just synchronized both Active Directory and Cisco ISE, ISE is using my server (AD) as an NTP server, everything is fine, but now I'm facing an issue "Status Summary: The operation took longer than expected. This may be caused by slow network connection or similar issues. Please check the connection tab status table and the AD Connector Report for details."

I could not understand the thing that is causing this issue.

Cisco ISE could resolve DNS names on server.

======> Only problem I could have and I'm not sure that it is the thing that is actually causing the issue is that my Windows Server clock is one hour forward Cisco ISE (They both have 1 hour difference in their clocks) despite that Cisco ISE is using my Windows Server as an NTP server.

Just to make sure I'm following along, could you please share the screenshots of the errors you are referring to? and also, could you please confirm that both ISE and the AD are showing the right time?

Here is logs for Cisco ISE.

I think it is something relative to AD Connector!
