If your Windows XP laptop has the Kbdclass driver configured in grand master mode, as in SMS 2003 clients, you may receive an error similar to:
Stop 0x0000007E (parameter1, parameter2, parameter3, parameter4)
To disable grand master mode for the Kbdclass driver:
1. Open a CMD.EXE window.
2. Type the following command and press Enter.
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Parameters /V ConnectMultiplePorts /T REG_DWORD /F /D 0
Instead to this workaround, you can call Microsoft and request the 926238 hotfix.
