P2P 2k Network Probs

SouperComputer

this is doin me sheggin head in.

2 Pcs (IBM-450 and Barb) Barb is a 233mmx

I have DSL and ICS setup on IBM under RASPPPOE

From the IBM, I can access all the shares on Barb, no prob and transfer files back and forth.

However Barb cannot either see the IBM or cannot connect to it (not found on server, blah blah) depending on what mood its in.

Its not an account problem as it was working fine for a while. Recently it has been giving me crap, like not connecing shares at logon, but work fine when I boot into windows.

I uninstalled all protocols and services on both machines and re-installed them, then re mapped the drives, worked fine after booting the IBM.

Now having rebooted Barb im at the original problem I speak of. IBM can see and acess Barb, Barb somtimes sees IBM and cannot access it or cannot see it, or claims the workgroup details are not accessible. But while this is going on, IBM can still access barb

Sorry if this is a bit of a rant, but its pi$$in me off!

can anyone help me, im considering refereshing the OS, but would rather fix it "properly"

TIA

ibm has 2 nics

1 goes to internet

1 goes to lan

firewall is on on both nics

turn it off on the one leading to barb only

SouperComputer

i only had the firewall on the DSL nic

its wierd, on IBM I click on network places, computer near me and it says "worgroup not accessible..." blah, blah, yet my shared drives on Barb can be acessed.

If i go to Barb now, I see both computers in netowork paces, but if I try to access it (IBM), it claims the computer is not accessible, wrong path!

i even uninstalled the firewall, no difference. checked for virus's on both machines.....nothing.


the network was working with the firewall in place before too

wreckin me buzz!

Possibly one of the machines is becoming browse master and the other doesn't like it.. Try and force one to be browse master and the other not.

Bit of a long shot, only really seen this problem before on win95/98 machines.

SouperComputer

yea, it feels like sumfin along that track.

how do I force a brouse master?

Gavin

sorry, I can't find the option for windows 2000. As I say, it was only with 98/95 I encountered it before. It was in the network properties on those OS's.

I just saw this thread and thought the same thing (browser) .. check your event log .. look for something that says that the computer browser service could not be started or similar ... you'll have to go into the computer managment screen and set it to automatic (in the services section)

SouperComputer

Thats kinda funny, I always say the same thing to others about event log, and do it on other' computers!!

anyho, services wise, nothing has been disabled since it was working fine, just rechecked my services and nothing strange there.

In the event log (on IBM) however, there is a couple of interesting errors:

1.

I dont usually look for help, as I like to figure out stuff myself.

But any ideas out there?

SouperComputer

there was a couple of NAT errors too, but im not too worried about them ATM

BigEejit

er... does ibm-450 have "obtain an IP address automatically"? (found under TCP/IP properties) or are you telling it what IP to use? ..

SouperComputer

its on DHCP, I thought ICS automatically fixed the Ip of the NIC that shares the connection?

Hmm
