I have a user who is getting an error when he tries to open up his mail DB. Error: The Notes server is not a know TCP/IP host. He is a LAN user and I checked his mail setting and they seemed fine. Also he is able to ping the mail server from his PC. Please help!

Hello,

We've had the same problem on 5.08 clients and it is usually one of two issues. Most here have been caused by DNS problems.

DNS:

Make sure the client is getting DNS resolution by pinging the Notes/Domino server by its Domino name(not by the server's IP address). If it times out then DNS on the client isn't working correctly.

Notes Client:

Under "User Preferences" change the TCP/IP timeout port setting from the default 5 seconds to 30 seconds. (Disabling all the other ports can help too, if you are using IP only on your network.)

Hope any of the above helps.

Make sure that Notes in the lower right hand corner is set to "office" and not "internet" or any other option. Hope this helps
