Hi all,

We frequently experience the following EM when connection to an application on our Server:

Event source TN3270E, Event ID 56, Event Type - Error, Unknown TCP error =6.

Can anybody tell me what the EM exactly means?

Sorry, none of above really helped me.
In addition:
We are using a Terminal Emulation call Web to Host from Netmanage which is installed on an Apache WebServer who connects to a Mainframe over a leased line. They use the emulation through their Internet Explorer.
About 400 users are using the emulation software and since 2 weeks 1 to 10 user are receiving this error message. Usually rebooting solves the problem. Protokol is TCP/IP.
