SQl2000 / VB6 ADO, cryptacquirecontext error
Posted on 2002-07-01
Hi Guys
Having a problem where i'm happily running my VB6 application against a sql2000 database.
My VB6 application will do a certain number iterations (reading from a recordset, and then inserting records into a table), and then it
will fall over with the following error message.
Run Time Error ='2147467259 (80004005)' :
CryptoAPI function 'CryptAcquireContext' failed. Error 0x8009001d:
(Error description unavailable)
At this point, I try closing the ADO connection, and re-opening, and I get the same error.
Whenever I try to load another windows program (i.e. Windows Explorer), I get a 'not enough memory to load program' error
I know that I have memory avaliable, (at least 80mb is being reported in the 'Free Physical Memory').
If I try running the SQL Insert statment in SQL Query Analyser, the insert works perfectly. (And I can also disconnect / reconnect to the SQL Server)
The only way to get my VB6 App to run the SQL Insert line is to stop the SQL Server process, and re-start it.
Obviously this is not a great solution, as my code is running on a client's machine which I do not have control over.
I've looked on newsgroups, and forums, and have come across a few references to this problem, yet none of them have had definative answers.
Can anybody help me please?????

I think that you have the protocol encryption enabled, which uses the CryptoAPI. Unless you need this, you should disable it.
Independently of this, I could solve some problems with the CryptoAPI by
1) ensuring every user had full permissions to all the Crypto Hives in the registry
2) ensuring that no invalid/unknown users existed in the registry permissions for that hives.

Thanks for replying so quickly.
I'm not explicity using the Crypto API, so how do I disable the protocol encryption??

Start the "Server Network Utility" on the "Microsoft SQL Server" menu (Start->Program Files is the default location). You will find the option in the first tab.

The option there does not allow you to explicitly set 'no encryption', only to enforece encryption.
I have tried various protocols and still no luck :(
