Windows XP Professional only allows 10 simultaneous connections to shares and printer spoolers. The eleventh user gets
|
|
a *System error #71* message. The unused connections get freed after 30 minutes which is a bit late since often you
|
|
just need a few files or to print some pages but this blocks the connection for 30 minutes.
|
|
|
|
To make things better, you can issue the command
|
|
|
|
net config server /autodisconnect:3
|
|
|
|
which sets the limit to 3 minutes. You can even set this to `0` to free a slot almost instantly.
|
|
|
|
This value can also be changed in the registry. The key is `HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters`.

The really evil can fly to [Google Cache](http://66.102.9.104/search?q=cache:kHQ_0PQXJDQJ:tachyon.zapto.org/binaries/antiwpa/LanServerNoConnLimit/patched.txt+srvsvc.dll+%226a+0a%22&hl=en&ct=clnk&cd=3)
|
|
and get a disassembled part of the `srvsvc.dll` with the needed changes to disable the limit. (Only works for XP-SP2!)
|
|
|
|
The last resort is to upgrade to *Windows Server*. Another thought might be to connect to the shares from a Linux box
|
|
and let the clients connect to this Linux machine.
