Hellow all, 

Has any user experienced this kind of problem?

i want to run a task server static group synchronization on my ESET Protect

but I have a problem like this

Failed to load data: Active directory browsing failed. Check input server parameters and AD availability.: Trace info: Failed to bind to the specified object (LDAP://tos.com/DC=tos,DC=com). Error code = 0x8007203a, The server is not operational. Error code: 0x8007203a

I've found the requirements in the following link.
