Hi Gobinath,

Check whether u have created the entry in hosts file for ur server. go to C:\WINDOWS\system32\drivers\etc & make an entry for ur server in hosts file

u have to give the ip address & host name for ur server in that file .

Hi Gobinath,

Check your SLD configuration. Looks like there is some problem with the parameters specified for your logical system..

The exception says it is not able to locate the host.

Thanks
