Hello Experts and thanks in advance! I'm struggling to figure out what the problem is on our network. We had a malware issue that we rooted out but have discovered since that DNS doesn't respond well to the first attempt but will immediately connect on the second.
For example: Let's say I want to open SharePoint. You go to the site and it will just sit and spin, but if you refresh right after your first attempt, it opens right up. Same thing with RDS and DameWare for remotely connecting. There are no bad entries in DNS that I saw and no errors in the log. I have tried building new servers with DNS and I still encounter much the same. I've scanned multiple times using several different AV and AM software and they are all saying my systems are clean. I can't really put my finger on it but I'm pretty sure this has to be a DNS issue.
