2 workstations. Both XP Pro. Desktop and Laptop. Cannot map the drive. I've been trying to sort this out for my client remotely but have tried everything I can think of. Both workstations are in my workshop connected to my network with the same workgroup. It doesn't seem to be the laptop at fault because I tried mapping the same drive from my main XP PRO workstation at my shop but still the same error so the problem is with the PC itself. I have changed the IRPStackSize as suggested below
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this issue, increase the value of the IRPStackSize registry entry. To do this, follow these steps:1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
If the IRPStackSize entry is not present in this subkey, follow these steps:a. Click Edit, point to New, and then click DWORD Value.
b. Type IRPStackSize, and then press ENTER.
Note Type IRPStackSize exactly as it appears. The value name is case sensitive.
3. Click IRPStackSize, click Edit, and then click Modify.
4. In the Data Value box, type a larger value, and then click OK.
Note Values may range from 0x1 to 0xC. These values are equivalent to 1 to 12 in decimal notation.
If the problem persists after you complete the previous procedure, increase the value of IRPStackSize more.
Still Same problem. I have uninstalled Service Pack 3. S
Still Same problem. I have also uninstalled all network properties eg. File and Print Sharing for Microsoft Networks, Microsoft TCP/IP 6 Internet Protocol TCP/IP, Client for Microsoft Networks. NWLink IPX/SPX Netbios Compaitible Transport Protocol.
Restarted and have reinstalled each one.
I also have increased virtual memory as also suggested in another post.
I'm running out of options and do not wish to backup and reinstall everything.
