Using: MS Exchange 5.0 for WindowsNT, NT 4.0

I have a Windows application (developed using PowerBuilder 6.5) scheduled to run multiple times a day which is supposed to send out email messages with HTML attachments. It seems to run at 5:50 am ok, but subsequent runs at 7:50 am, 9:50 am, ...5:50 pm usually fail. There are several other scheduled Windows apps that send out emails which run later.

Here's the error message I'm getting:

Cannot logon to mail system. MAPI error code: ActMsgE_LOGON_FAILED

But when I manually run the program, the email message does get created and sent without any problems.

Any ideas?
