ADO Connection Open fails with error -2147467259 when MS Access database under Source Safe

gm
Immediately after generating the Access application from the Source
Safe project I get:

"-2147467259 Could not use ''; file already in use."

If Access database closed and then reopened I get:

"-2147467259 The database has been place in a state by user
'Admin' on machine ..... that prevents it from being opened or
locked."

This error will then persist - even past a machine reboot and compact
and repair of both application db (without source safe removal) and
'server' db. If I remove the Access application from Source Safe
the ADO connection opens fine. (Might have to close database and
reopen it to get it working the first time after eliminating source
safe.)

I do not appear to be short on memory. Am using:

Access 2003 with sp1
Source Safe 6.0d
Windows XP Professional with sp2
Database in Access 2002-2003 format
Microsoft ActiveX Data Objects 2.7 Library

I have isolated error in test database with just one table and one
form. Test1 fails under source safe while Test2 - which avoids use
of the offending open command -works regardless of use of source safe.

Any illumination on this would be appreciated. I have found the Source
Safe & Access combination hard going but I do not want to loose source
code control. This issue has undermined my confidence in these tools
yet again. Many thanks.

I have a business object (c#) running on an app server that talks to my sql server 2000 (2 separate physical machines). If sql server gets restarted (i.e. someone kicks the cord out of the wall on the db server and it needs to be restarted), the connections that IIS is maintaining seem to be invalid. If someone can verify that or explain a little about how the internals of that works, that would be educational for me but I'll take it on faith...

Hello, I'm currently trying to implement a simulation program with Kamaelia and need a reliable TCP connection to a data server. From Twisted, I know that a method is called if the connection fails by whatever reason. I tried to get the same results with Kamaelia's TCPClient component. If I start up the component and try to connect to a closed TCP port it fails and sends a message out of the signal box, that's okay.
