xp logon slow

XP logon slow in child domain

Situation: The Company just created a child domain for HR. XP computer logon takes over 5 minutes.

They did check these:

Make sure each computer points to the internal DNS.
They can ping the DNS server.
Disable all protocols except TCP/IP.

Analysis: By default, a computer running Windows 2000/XP registers only one name in DNS, which is hostname.PrimaryDNSSuffix, for example bob.chicagotech.net. However, if the computer belongs to a Domain Name Server zone, for example ms-mvps.chicagotech.net with a name that is different from the Microsoft Active Directory (AD) domain name, chicagotech.net, the computer should join both domains during startup.

Resolution: Select the "Use this connection’s DNS suffix in DNS registration" option in the DNS tab of Advanced Server TCP/IP settings. The ipconfig /all displays like this;
