This may block applications that try to send e-mails via SMTP.

When the reports run they sometimes work with no errors but about 7 out of 10 times they will fail with a VB288 SMTP error: Critical Error: VB288 Internal Error. Source: com TBSMTPSendMail.DoSend, Description [288], Line: 0 When the same reports are run from the server direct they work every time, and networks have confirmed there are no issues on the LAN, I have also tested SMTP from the server to send e-mails which works fine as well. I have tried a reg hack to increase SMTP timeout on the servers and this hasn' t helped either and the CPU on the citrix servers are not spiking over 60% when sending the mails? The vendor do not currently support the version of the app we are using anymore but did advise that the DDE ' destination is busy' ??? We are currently running on ESX3.5 with VM' s Win2003 PS4.5 (The app is dedicated on the servers in question) Any ideas would be a great help as I' ve hit a brick wall Thanks in advance Al -- This message has been scanned for viruses and dangerous content byMailScanner, and is believed to be clean. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
