Could not use ''; file already in use
I need urgent help. I cant get my hosting to resolved it.. says
if it was a simple problem it would of been fixed? says the database
is in full control but if more then one person accesses or
I open 2 connections it fails.
it was all working fine before the WIN2000 with sql97 and MDB
access was upgraded to a WIN2000 with a separate sql2000 server box
and a faster web server box
'using the newer open methods to MDB
response.write "This should work, multiple access (opens) to a MDB<br>"
Set objConn2 = Server.CreateObject("ADODB.Connection")
objConn2.Open "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("\stats\data.mdb")
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("\stats\data.mdb")
'do nothing just a simple open and close
Set objConn = nothing
Set objConn2 = nothing
response.write "MS ACCESS MDB - multiple opens to the same DB Successful!<br>"
ERROR given as follows
Microsoft JET Database Engine error '80004005'
Could not use ''; file already in use.
/multimdbtest2.asp, line 10
this is a simple ASP for testignonly the real code does 2 connections
and worked fie for 12 months on a older server setup.. so I dont think
its anything to do with coding after that fact.
ANY CLUES ANY ONE?

I get this error frequently while testing. It usually occurs when I have an object(Word, Access, Connection, etc.) open and the application fails due to a programming error. This leaves the object "hanging around" in the operating system since the "close and set to nothing" code was not executed. It makes the object look like you're already using it and cannot have a second copy of it.
If you're having this problem on a new release of your PC/LAN/Server, check to see if the ODBC connections have been marked "reusable". I've only run into this once and don't remember if they should be set to yes or no.
If the object in use was on my PC, I can clear the error by signing off and back on again. If the object in use was on the LAN/Server, I have to sign off and power down the PC to clear the error.
I try to leave any application objects(Word, Access, etc.) minimized but visible. If my program fails, the application can be manually closed without rebooting. Saves a lot of time.
Good Luck,Bruce Baasch

I know this is an old thread but, If someone else finds this because of the same error the fix might be very simple for you and this could help... This error can be generated when the containing folder of the MDB does not give the IIS User Account authority to read and write in the directory. Right click on the folder and select the security tab. After doing so you will want to add the user which is something like (IUSR_MachineName). The only privileges that should be needed is Read & Write, no execute needed in many cases. Well I hope that this helps someone... Cheers!

Do following things and your error will be solved.
In most of the cases this error comes due to disabled impersonation in web.config file.
Add following things to enable impersonation in web.config file and your error will disappear.
<identity impersonate="true" />
