I compiled PHP4 under WinNT 4.0, and php_mssql70.dll, and loaded it under IIS4. I can connect to a MSSQL 7 Database, select database and close connections perfectly. But when I call mssql_query, I get an alternate error: at first, the query goes perfectly. Then I press "Refresh" in the browser, and I get an error: "PHP encountered an Access Violation at 00000000". Then, after refreshing again, the query is made perfectly... and so on, I alternate an error with a normal result.

I close all open connections. In case it helps, I couln't find the headers "sqlfront.h" and "sqldb.h" needed by php_mssql70.h in the original PHP4 tarball, so I used those from version 3.0.16 and everything compiled fine (wooops!)

I hope it helps, I can debug it myself if you give me some hints (I've little time).
