Remote user cannot connect.

Hello everybody

We have SAP has on Windows 2003 + SQL 2000 in clustering environment with lease lines used for fallback purpose.

when one Lease line is down then all the traffic move to second lease line. When this fallback happen that time remote

location user can ping to SAP production server but cannot login to SAP production server,same time they can login to other SAP system like DEV, Quality. Local user has no problem they can login to SAP production server that time also without

any problem.

When I move the resources to another node it working fine. or if restarted the server it work fine.

At SM21 log is

Operating system call recv. failed (error no. 10054)

Please suggest me where to check the problem?

Thanks

>>When I move the resources to another node it working fine. or if restarted the server it work fine.

Looks like firewall issue, ping is not correct tool to test the connectivity please use

telnet <server_name or IP> <port>

and post the results.

Hi!

Thanks for reply.

In the network, TCP/IP setting, In Default Gateway there are two entries.

first is Router IP , second is Firewall setting.

{telnet <server_name or IP> <port> }

which port to be telnet?

second thing, if the firewall issue then I dont know why user can log on other system like development, Quality.

Please suggest.

Thanks

you need to telnet your SAP port (ie Message server and getway port)

You can block the services using ports on firewall, doesn't mean that one service is working mean also work another service which is using different port.
