Question : Exchange 2003 not using new DC- Messages pending submission backing up

Greetings,
  I have a 2003R2 DC I added to the domain to take over the role of my old DC.  I transferred all FSMO roles to new DC about a year ago.  Last night the old  DC died and now exchange messages are backing up in Messages Pending Submission queue, and  not being routed to our users. (Exchange 2003 standard-stand alone server)  
   Also,(if this is related or not I don't know) but when people try to log on to the network their login is taking a very long time to process and get them to their desktop.)
GC, DC, and Config on exchange server> directory access properties all point to new DC server.
Recipient Update Services point to new DC as well.  New DC is also functioning as DNS/DHCP
 what am I missing?
