Hi all,
I will try and explain this as best as possible.....
We have approx. 40 work stations in one building all connected via SBS 2003 SP2. While logged in as administrator I can normally access the hard drives of the various stations with:
 \\ station name\c$
The stations all have XP Pro, some with SP2 and some with SP3.
For some unknown reason certain stations are blocked. Firewall for XP is set as policy for all, those that I can access and those that I cannot. Any suggestions as to how to cause proper access to those that have "blocked me out ?
Please see attached screen capture
Thanks up front,
DR

Go ahead and give this a try.

   1. Click Start, click Run, type regedit, and then click OK.
   2. Locate and then click the following registry subkey:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
   3. Click Edit, point to New, and then click DWORD Value.
   4. Type IRPStackSize, and then press ENTER to name the value.

      Note Type IRPStackSize exactly as it is displayed. This is case sensitive.
   5. Click Edit, and then click Modify.
   6. In the Data Value box, type 30 or any value max of 50, and then click OK.
   7. Restart the machine


Let me know if it helps.

Just a note, do it on the machine you're trying to connect to as well.

I believe this simply has to do with the amount of inbound and outbound connections any one machine can make at a time. Increasing this registry number subsequently increases the number of connections allowed.
