From the Symantec site:
Q: Which Symantec products will the product update apply to?
A: The product update applies to customers who use Symantec Client
Security, Symantec AntiVirus Corporate Edition, and Symantec AntiVirus
Enterprise Edition if their client systems are not members of a Windows
domain. This is because Windows XP Service Pack 2 does not enable the
Windows Security Center or the Windows Firewall if it detects that the
computer is a member of a Windows domain. It also applies to
administrators who choose to enable the Windows Security Client in a
domain. Product updates for other Symantec products may be released in the
future but none are scheduled at this time.
As stated in the answer if a windows XP client is joining a Domain SP2
won't enable neither the Security Center and Firewall. Does somebody have
any mor information about this?
