After transferring the FSMO roles to our 2008 R2 server and making it the new PDC. I was unable to get the 2003 server to graciously demote as DC, I then used the dcpromo /forceremoval, since then we are unable to reconnect the 2003 server to the domain, All the workstations can no longer connect to Exchange (also hosted on the PDC at this point), when running a nltest /dclist:domain command the domain cannot be found.  I have attached a copy of the dcdiag, any help would be appreciated.

You must setup the DNS role on your DC, seems is not working
"Name resolution for the name isatap timed out after none of the configured DNS servers responded."

Check firewall rules, open DNS console and check you see your dns zones. dcdiag doesn't found any DNS servers.

The BPS logs are in xml format, is difficult to red but some messages can be extracted.
"<Message>Could not find a forest identified by: 'crossroads.local'.</Message>"
this points to a DNS issue also.

Disabled local firewall as well as created a rule in external firewall to allow all internal traffic (just in case). Opened DNS console and am able to see the forest for the domain just fine. When trying to connect the 2003 server to the domain it states

DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain crossroads.local:

The query was for the SRV record for _ldap._tcp.dc._msdcs.crossroads.local

The following domain controllers were identified by the query:

crm-dc.crossroads.local
hp-crmdc.crossroads.local

Common causes of this error include:

- Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.

- Domain controllers registered in DNS are not connected to the network or are not running.

How many domain controllers do you have now?

You must check the DNS zone _msdcs.yourdomain.com for staled or wrong records pointing to non-existing DCs, do the same in your domainname.com zone for NS records.

It looks like I have cleared the largest hurdle.  Turns out the issue had something to do with netlogon and sysvol shares not replicating correctly. I was able to rebuild them and now computers are able to join the networks again as well as exchange seems to be functioning again.  I would like to thank you for your help regardless Walter.
