I call OpenFile to access a file across a network, using an IP address. If the network connection is not established, there is an intolerable delay in the response to the Openfile call (45 seconds on my machines). This seems to be the case for the execution of any code which results in a call to CreateFile (OpenFile, FileExist, etc.) During this delay, the machine's resources seem to be frozen. How can the connection be checked prior to the call? How can the operation be aborted if the delay is too long?

When connecting to an NT server from an NT workstation over the network, and using Net Use with a valid password and user name, the connection is established correctly on the first attempt. If the connection is broken and re-established, subsequent attempts to connect using Net Use cause error 1326 "logon failure: unknown user name or bad password". Must restart the workstation for Net Use to work. Has anyone else encountered this situation and have a solution?
