Unexpected TCP/IP error func: 0009h error Notes: 1C5B,NTI: 1000h, Stack: 0000271Dh

Hi Guys, I got a strange problem Notes 8.5.1 Basic Client on Windows 7 64 Bit Machine.

User can ping our Server and open Databases over Internet on the Server but if he trys to replicate he gots the following Error:

Unexpected TCP/IP error func: 0009h error Notes: 1C5B,NTI: 1000h, Stack: 0000271Dh

I find that this issue sometime happens on Notes 6x Clients but didn’t find anything regarded Notes 8.5.1.

Is this may a know problem and what can we do?

Thanks a lot for your help.

Check desktop firewall if Notes is blocked.

Hi Thomas

I am seeing this error “Unexpected TCP/IP error func: 0009h error Notes: 1C5B, NTI: 1000h, Stack: 0000271Dh” at a Notes client R8.5.1 on replication, posted to the client log.nsf… The client has a configuration for SMTP third party mail that has worked flawlessly for months, email before lunch OK - after lunch… this error. This error occurs on the “Receive Internet mail” item on the replicator page.

Did you resolve your issue, what worked?

Thanks…!!
