Windows Home Networking Problem

I have 3 machines A, B, and C connected through a hub as follows:
A. Win2k Pro
B. WinXP
C. WinSomething
The uplink of the hub goes to a LinkSys router and out to the rest of the
world.

I installed Win2k3 Server on machine C by sharing the DVD from machine B.
Everything went fine.

I then decide to make C a domain controller so I run dcpromo and allow it to
install DNS. The AD setup is moving along ok, until the C trys to copy
dnsmgr.dll from the DVD (on computer B). It complains that it cannot find
the file. C is still looking as I write this.

Now the state of the machines is as follows:
A can ping B and C and anything on the internet
B can ping A and anything on the internet but NOT C
C can ping A and anything on the internet but NOT B

I am pinging by IP number so name resolution isn't an issue. All NIC's are
manually set to 100/half.

I have tried changing ports on hub but other than that, I don't know how to
troubleshoot this any further. Networking is not my specialty. Any
pointers would be greatly appreciated.

Thanks in advance!

Save yourself some hassle and nuke machine C, and then
copy the 2k server CD to the local hard drive. Once it
is there re-run setup and let it finish the copy.

As far as the machines being able to ping, I would check
to see what they are getting IP wise.

start, run, cmd, ipconfig /all|more

Make sure all machines have the same subnet and gateway.
If they don't (and assuming your Linksys is the DHCP
server for your network release and renew all machines
(ipconfig /release , ipconfig /renew). You may need to
reboot the Linksys for some odd reason as well.

Worse case scenario, you can manually set all the IP
addresses on the machines to the same subnet and make
sure they will all talk correctly then.

I have run into many issues trying to run installs from
a "shared CD". It is just easier if you are installing a
server to have the CD on the hard disk (provided it
doesn't have an internal CDrom...which aren't really
expensive by the way...hint hint...

Hope this helps!
