new server 2003 slow login NOT a DNS problem



we have a remote site that had been using Windows 2000 servers until
this week...

we replaced them with Windows Server 2003 R2 Standard, these servers
are in the DMZ behind an IPCop firewall...

the SBS2003 which controls the domain there is in the LAN. it is the
only DC on site, and handles internal DNS.

I can log in to one of these servers and nslookup all night long with
instant and correct replies.

Server1 is in the DMZ at 172.17.176.5 - the SBS is at 172.17.167.3...
and I can put the SBS in to explorer and it instantly brings up the
SBS's shares.

My IPConfig shows:


C:\Documents and Settings\Administrator.DOMAIN>ipconfig /all

However, I wait for 5 minutes of 'Applying your personal settings'
when logging in with domain user information - the authentication
seems instant, but (from what I've read) the Group Policy is not
properly getting through...

The firewall has been opened to allow ICMP from server1 to the sbs2003
dc in a desperate attempt to find some little overlooked detail, no
luck.

The firewall is opened between these two machine as follows:
UDP :137(NETBIOS-NS)
UDP :138(NETBIOS-DGM)
TCP :139(NETBIOS-SSN)
TCP :445(MICROSOFT-DS)
UDP : 53(DOMAIN)
UDP : 389(LDAP)
TCP : 636(LDAPS)
TCP : 88(KERBEROS)
TCP : 135(EPMAP)
TCP : 3268
TCP : 1025
UDP : 88(KERBEROS)

So - DNS works, I can access shares through the firewall, I can even
ping, but still I'm getting a 5 minute hang - anyone have any ideas?

thanks all -


Richard
