XP Pro Can't Browse Internet

[MJD]

I have Windows XP Pro machines in a networked domain
environment and have not experienced this before.
Recycling older PC's and putting XP Pro on them has been a
piece of cake. Internet explorer works fine...until now.

I have two machines (Celeron/WinME and Celeron/Win98).
When upgrading, I chose to convert to NTFS. But both
machines seemed botched when done so I reformatted hard
drives and did a new/clean install again using NTFS. I
joined domain, can browse the network, access Exchange
email, ping the domain, but cannot ping internet sites nor
open ANY web page. The only other software installed is
Office 2000 on both machines and Computer Associates
Antivirus client on one.

Event viewer says that iexplore.exe is a hungapp.,
Automatic Certificate Enrollment failures (Event 1054),
and Userenv (Event 1054) cannot obtain domain controller
name.

I have tried manually adding windows and iexplore updates,
I have tried to repair internet explorer, I have
reinstalled internet explorer, I have changed settings
numerous times within network settings--hard setting the
IP address, etc., but still to no avail.

Help!!

I have had some problems with XP on a SBS2000 network.

1) try pinging the IP address of a web site.
2) Try pinging the local IP address of your firewall/router
3) try pinging the untrusted side of the firewall (assuming you have a
static IP address or know what the dynamic IP address allocated is.)
4) If 1 works but you unable to get it to ping the name, then it may
be your workstation DNS settings. in which case try making your ISPs
DNS address top of the DNS addressing on the workstation. If this
cures it you need to change the DNS server to enable forwarder, take
out the "." lookup if it exists, and (as a belt and braces) add the
DNS server address to the hosts lookup table.
