Internet Connection Sharing problem

I have 2 PCs both running Windows XP Home, and they are
connected together by a twisted Cat 5 cable, and I use
Internet Connection Sharing on 1 PC to connect both to my
ADSL connection. The Host machine is an old 500Mhz
Pentium 3 PC which originally had Windows 98 on, but I
upgraded to XP Home last summer (but did a complete
format and install), the client machine is a year old HP
Pavilion which came with XP Home already installed.
Everything has been running fine since about last August
until about a month ago. The ICS keeps failing when
booting the computers, previously, I could power up both
together and I would be able to browse the internet fine
on both PCs. Also, if I had to reboot the host PC, it
would just stop the clien accessing the internet while
the host rebooted. Now, either scenario means the client
can't access the internet, the only way to do it is to
power up the host, sign on to one user only (I have 3
users who use fast user switching), connect to the
internet, then after 5 minutes or so, power up the
client. I have to go through this every time I reboot the
host. I have run Virus scan, Ad Aware, Spybot, on line
Symantec scan, and yesterday I used the Windows Repair
function, and after 7 hours of backing up, repairing, and
putting the Windows patches back, it is still the same.

Whether it is any help, the host also seems very slow,
with a svchost.exe process with a user of System seems to
be running at 90% + usage with a climbing memory usage,
and I am getting DCOM and IPNATHLP errors in the event
viewer, although I believe that these are common with ICS.

The Network Address Translator (NAT) was unable to
request an operation of the kernel-mode translation
module. This may indicate misconfiguration, insufficient
resources, or an internal error. The data is the error
code.

These error messages appear whether the client can access
the internet or not. I found a Knpwledgebase article on
the DCOM messages, Q290398 but this only refers to IIS
servers!

Thanks for any help!
