We’ve been experiencing problems connecting to AD from our web application since July 7<sup>th</sup>. this is critical time for the business users.
In our application’s log we see multiple occurrences of the following error:
2020-07-12 21:29:43,156 [115] INFO AppLog - GetUserInfoStatic :chekale
2020-07-12 21:29:43,156 [115] ERROR AppLog - SearchFiles():Unknown error (0x80005000) at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)
2020-07-12 21:32:04,930 [73] INFO AppLog - GetUserInfoStatic :celedfe
2020-07-12 21:32:04,930 [20] ERROR AppLog - BusinessUnit():Unknown error (0x80005000)
2020-07-12 21:32:04,930 [73] ERROR AppLog - ProcessName():Unknown error (0x80005000)
A quick search for the error code returned:
“It's not unknown, 0x80005000 means that "The specified directory service attribute or value does not exist". It will sometimes occur under a heavy load, when the global catalog server may fail to authenticate a client by using Kerberos.”
There were no changes on the application side, it is impacting multiple users.
Could you please look into this issue and advise? Your prompt response is greatly appreciated.
Additional Details:-
The below error is intermittent, a user is not being authenticated against AD so the exception is thrown.

Solution1 Tried:-
We try to fix this by going to Advanced Settings of the IIS App pool of your application and setting "Load User Profile" option to True. - Still monitoring on this issue..
Solution2 Tried:- App pool rest works always and again issue re-occured.
What would be the right solution to fix the issue?
Appreciate your help.
