shared folder troubles

I have three xp machines all with SP2 current on all updates.  Two desktops and one laptop.  I could access shared folders last week on all machines.  

Today the laptop was plugged back into the network and I can't access shared folders.  I can ping all machines all from each other and all machines have internet.  

I can't access any shares, not even C$ on any of the desktops from the laptop.  The desktops also can't access any shares on the laptop.

The laptop and one desktop are running symantec corp 10 the other desktop is running Norton 2004 antivirus.  Like I said earlier they worked last week.  

I tried manually configuring the network addresses and DNS and still had same results ping but no access to PCs from the laptop and vice versa.  

The two PCs communicate fine though.  I'm running a virus scan on the laptop to make sure it didn't get infected over the weekend.

The only change I could get the user of the laptop to fess up to was that she had Wild Blue highspeed installed at her house and the kids played online games over the weekend.

Hi dcsdave,

norton antivirus or internet security     what other firewall appz do you have installed and is windows firewall disabled,    what is the exact error you get when you try and access a share

dcsdaveAuthor Commented:
Just Norton Antivirus and just client antivirus.

Only windows firewall no other third party software.  I have tried disabling the firewalls and still had same errors.

On a mapped connection I get the error that states the network drive is not available but it shows that it is connected in "My Computer".

The error I get for the shared folders is similar but adds the case where I might not have permission to view the folders.

I will be at the clients office in the morning and I can post the exact errors then.  

no worries     disable firewalla before troubleshooting though

Sorry for the late post.

The error message I get when I click on the shortcuts that I have setup is:

"The drive or network connection that the shortcut "bla bla bla" refers to is unavailable.  Make
sure that the disk is properly inserted or the network resource is available, then try again."
I can't remap the drive or browse the network.  I made sure that the defaul setting for Netbios was checked in LAC properties also.

Would a repair of the winsock help this issue?  Iv'e used that to fix internet connections before.

i think winsock usually jus does internet but hell try anything!

can you get any ping responses from any where including the loopback
dcsdaveAuthor Commented:
I can ping all machines on the LAN and all internet sites I tried.  I haven't tried the loopback though.

I'm going to try an XP Repair and I guess if that doesn't work I'll have to format reload.

The real pisser is that they use a bunch of proprietary software that is a chore to load and configure.

I will be performing the repair/reload this weekend, so any suggestions before then would be greatly appreciated.

Thanks again for your help.
i would place money on it that symantec has something to do with it, but then saying that, i blame them for the majority of things in life!

here a P2P site you may want to have a quick run through from Fatal_Exception

Thanks for your help Jay Jay.  

I just ended up totally rebuilding the network and also disabling the firewalls.  

Kind of funny how Microsoft's firewall doesn't allow file and printer sharing even though the exception box is checked to allow.  

Go figure.
