I have a unique issue with a current server 2008 r2 deployment that is a member server on our internal domain. When I create a folder and set the permissions from the security tab, if I choose to lookup in the active directory name list and then hit the "Find Now" radio button, it takes really long to audit and present the users and security groups.
I tried this with a couple of the domain controllers and they are really quick to present the audited users.
I have verified my dns settings and did some nslookups to verify that computer names and such are queried quickly.
To clarify this server has a static ip address using the ipv4 settings or tab from network connections. ipv6 is left checked on.
Is there anything i can check to verify if there is an issue.
