I'm running two machines and an HP Laserjet off the router. My notebook
is running XP Home SP1, my desktop XP Pro SP1. I can happily share
drives and folders from each machines internal HDs, and also their
external USB ZIP drives and 1GB flash drives.
What I can't get to work is sharing the external USB HDs attached to
the computers.
When I try to connect to them, having enabled sharing, I get an error
message:
"(drive) is not accessible. You might not have permission to use this
network resource. Contact the administrator of this server to find out
if you have access oermissions.
Not enough server storage is available to process this command."
As I'm logged in as an administrator, and the other drives are set up
the same way, I'm guessing that the last sentence is the critical one.
Has anyone got any thoughts on any tweaking I might do to get this to
work?
I thought about this a while, and then dived into the system log to see
if there was a clue in that. Sure enough, I found several
EVENT_SRV_IRP_STACK_SIZE errors.
The solution is to go to the registry and change the setting (which
wasn't actually present on either of my machines):
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\IrpStackSize
This should be 15, as I say, it wasn't there in either machine, so I
created a DWORD key, set it to 20, re-booted, and everything worked.
The same value was fine on both the notebook and desktop.
I hope this may help anyone else bumping into this issue.
