Multiple sites and slow logon
Posted on 2008-11-06
I started my new job as support engineer last month. The company I work for has a site in Belgium and in The Netherlands. One of the complaints I get a lot is that loging on to Windows can take long sometimes (2/3 minutes). Sometimes the logon screen freezes. At other times the Applying your settings windows is shown for a long time.
Both sites have a domain controller (DC-NL and DC-BE). Now I did some tests with a spare laptop. I logged on 10 times (after restarting the machine completely each time). Then I looked at the LogonServer environment variable. 4 times I was authenticated by DC-BE and the other 6 times I got authenticated by DC-NL. Oh yeah, I'm in Belgium by the way :-)
I think this is the cause of the slow logon. Now I've googled a bit and from what I can tell (I'm not an MCSA/MCSE) the best way to handle this is to create multiple sites in Active Directory. Currently there's only one site there (Default-First-Site-Name :p hey, that's how they set it up, not me!). If I get it right I need to create 2 sites and then move both DC's to their proper site. This way, depending on the IP I get I get authenticated to the nearest DC...
Is this correct? I've never done this before and I'm not sure of the impact doing this change. So, if I'm correct, can someone also give me some tips and tell me the dangers of making those 2 sites?
