I&#039;m receiving some inconsistent error messages when attempting to upload files to the server through asp.<BR>On my machine and several others the code works fine, on others the upload code is inconsistent.<BR>On the first attempt at uploading the file - the user will receive an "invalid procedure call or argument" on midb, the second attempt will normally fail, and the third will succeed. same file, same code.<BR>One user is receiving a http1.1 400 bad request errors.<BR>The server is running iis4, clients who fail are w2k, ie5+ machines. Clients who succeed are nt4, w2k, ie4, ie5, ie6.<BR>Any ideas would be appreciated.
