Well, my brain is hurting once again, I have run into a new problem. The past few weeks our system response time has deminished pretty noticiably. Most noticiable is the amount of time it takes to get working from login to opening cms.
All of my system are new and/or have fresh OS's. I have virus protection, and a web filtering solution in place and I know my systems are clean and locked down fairly well. I have ran reports to make sure we are not having bandwidth issues, and to verify packet loss and jitter time. All of the reports looked clean, most of our sites bandwidth utilization is under 50%.
We are really only experiencing the issues even locally an not over vpn. We have approximately 140 pc worksations and 50 thin clients. The thin clients seem to be working normally, and it only takes about 1 ful minute to login to the terminal server and launch our applications. I think this is normal and OK....
Our domain controller is our AD, DNS, DHCP, and BACKUP EXEC server. Our exchange server is also running AD, DNS, BES, and YES I KNOW THIS IS A BAD IDEA. Is there a way for me to measure or clock what is causing the slow login times? Typically procedure:
1. Login to PC Workstation
2. Pass-through to citrix apps
3. Login to CMS Application
Should I build 2 new domain controllers and only use them for one purpose to authenticate AD users, dns, and dhcp? What are your thoughts?
Thanks in advance.
