Hello All,
We are using the exchange server 2019 in our environment. Suddenly None of the users not able to login with Mail server.
We have tried with Multiple users and domain admin accounts, No luck.
So, we did the restart of server. After restarting the server users able to login with the exchange server.
We are not able to find any root cause for the issue. Kindly share your ideas what will be the reason for the service down.
We have analyzed the event viewer found Event ID 1006 "Windows could not authenticate to active directory service on Domain controller(LDAP Bind function call failed)
Note: At the reported time we are not having any issue with our AD.
Looking for all your valuable inputs and revert on this.
Regards,
Loganathan. R
