You have a type-o in either the manual configuration or the DHCP
configuration for the PC's default Domain Name. It's taking so long to log
on because DNS has to time out looking for the wrong domain (xxxxxx.cm).
Change the .cm to .com in the appropriate location.

Manual Config
System Properties
"Computer Name" Tab
"Change" Button
"More" Button
"Primary DNS Suffix of this Computer" Text Box

DHCP
SCOPE Options (Could be Server Options or Reservation Options)
Option "015 DNS Domain Name"
