C0000006 External Exception Errors
C0000006 on Local Area Network:
When receiving this error in a Local Area Network (LAN), it is generally an
indication the station is no longer connected to the network and it has lost its
connection to the server. It is recommended to troubleshoot the connection by
checking cabling, any hub or switch and the Network Interface Card (NIC) on any
station with this error.
This error could also be caused by anti-virus programs that
are intended for home users, such as Norton/Symantec anti-virus or Internet
Security. This type of solution does not support network application such as
Compulink and interferes with network packets.
We have also seen this error when other software such as RLI is accessed at
the same time as Compulink.
C0000006 on Wireless Devices:
If you are receiving this error using a wireless device, it is generally an
indication the station is no longer connected to the wireless network and the
wireless signal has been lost. This error is not critical with most applications
running locally such as Internet Explorer (Internet) and Microsoft word.
Even if your wireless device loses connection for a fraction of a second,
Advantage Software will no longer be connected to its source.
Boosting the wireless signal may or may not help avoid dead spots in the
wireless zone. It is recommended that you use Microsoft Remote Desktop (RDP/Terminal
Services) to access your files on the server. Once an RDP session is used to
facilitate the connection, if the wireless signal is lost, the Advantage
software will continue to run on the server. By reconnecting to the session, the
user can continue the database updates without interruption to Advantage
software.

Terminal Services Shared File Bug Fix
The network redirector mrxsmb.sys creates one data structure per computer for
every user that accesses a shared file on a Win2K system. The redirector
per-computer data structure causes problems when a Win2K system is configured as
a Win2K Server Terminal Services server and multiple Terminal Services clients
access the same file. To properly maintain connection information, the
redirector needs one data structure for each client session. In the current
implementation, when two or more Terminal Services clients open the same file
and one of the clients closes the file, the redirector incorrectly closes the
connection for all Terminal Services clients. You can find documentation about
the unexpected behavior in two Microsoft articles: "Programs Run from Network
Share on TS Close or Generate Errors" (http://support.microsoft.com/?kbid=294816)
and "PRB: 'Error reading file' Error Message on Windows 2000 Terminal Services"
(http://support.microsoft.com/?kbid=299603).
Microsoft now has a permanent solution for this problem, which exists in all
versions of Win2K through SP4. Call Microsoft Product Support Services (PSS) and
ask for the June 4 version of the redirector components mrxsmb.sys and rdbss.sys.
These new components have an option you can enable to create data structures on
a per-user, rather than a per-computer, basis. On Terminal Services servers,
after you install the new redirector, you need to activate the per-user data
structure feature by modifying the registry. Locate the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRxSmb\Parameters
registry subkey, and add the value entry MultiUserEnabled:REG_DWORD: 1 in
the right pane. Note that this modification is unnecessary on Win2K systems that
aren't configured as Terminal Servers. For more information about this problem
and solution, read the Microsoft article "Problems When More Than One User
Accesses the Same File Through Terminal Services" (http://support.microsoft.com/?kbid=818528).
