Hey all, we have a 2003 server (server1) which used to serve as our main DC, DNS, and DHCP and also held all our FSMO roles
We recently set up two 2008 boxes (server2 and server3) and promoted both to be DCs and moved all FSMO roles from server1 to server2
We also set up DHCP on the new server and made it authoritative and set up the DNS scopes to be server1 and server2, so when we do a ipconfig /all on any client machine it correctly points to server1 as its DHCP provider and server2/3 for it's DNS
So in an attempt to remove server1 from our environment and make sure everything is running properly from server2/3 I turned off server1 and within a day started noticing some odd issues on our network....slow file server access, internet latency/slow websites, etc.
nslookup for a client PC does point to server1, when I do a 'set' to see which logonserver it is using some PCs do point to server1 and others point to server2, but a reboot of those PCs make it point to server2 or 3...but still doesn't fix the above issues..
Not sure whether it is a DNS/DC/DHCP issue or what at this point...any ideas?
