Seems like i have a DNS issue and i can't figure what direction to go in. It ssms like teh DNS server (Primary) operated just fine for 4 or 5 days then i start to get errors at some point and the log fills up. When that happens, all my users experience extremely log login times (4 minutes plus). The errors that arise in the logs are 4011 and 4015. This server is a DC and also holds the FSMO roles (not sure if this is a bad thing or not). I also have a secondary DNS server installed but not really sure what good it's doing me. Should i move DNS to a differnt server? Does it have to be a DC? Or should i try something else? Any help is appreciated. Thanks!
