Thanks for the reply I did check logs and now its working I did change services butnow I want to know how can I establish connection between client machine to server
Run the following command from cmd by cd C:\Program Files\PostgreSQL\9.1\bin directory of postgresql
psql -h ip address dbserver -U username -d dbname -p port
Ex:
psql -h 192.168.0.110 -U postgres -d postgres -p 5432 (From other system ip entry should be present in pg_hba.conf of postgresql)
