Our config is currently:

1 Windows 2000 domain controller running ISA2000, dhcp, dns 1 Windows 2003 domain controller as main file server, prob cert server as well, dhcp, dns 1 Windows 2008/Exchange2010 domain controller as Exchange server, DHCP,DNS

Currently getting FRS errors on files server journalwrap error Currently getting FRS errors on othe DC's can't replicate from above

Exchange DC holds Schema, rid,pdc, and infastructure roles File Server holds Domain namaing operation master role

WOW, I didn't set this up, just inherited it. Am I right to assume that fixing the FRS errors is #1, what do I need to do for that? set enable journalwrap auto restore in registry?

Demote W2000 domain controller, should that have any implications for ISA? We have Forefront to be deployed but that's another day

Transfer Domain Nameing Role to Exchange server (I know or think having an Exchange server as DC isn't best practive) We will be getting another server W2008 to replace current file server and I thought it could takeover all roles once deployed

Demote W2k3 file server and then raise functional domain level to 2008

Am I missing anything other that the sense to walk away?

Thanks
