I have an old AS/400 server running OS/400 V3R7. I was earlier able to connect with it through Windows PC using NS Router. This AS/400 server was not being used for quite some time. Now when IPL was done and tried to connect the PC through NS Router, connection could not be made. However, connection could be made through TCP/IP. But unfortunately due to power failure while AS/400 was running, shut down was started as the UPS was not giving sufficient backup time. But before the server could shut down completely, UPS stopped and so AS/400 could not have complete normal shutdown. After this when IPL was done again, it is not getting connected with PC. The message comes that License server is not available though the PC is able to ping with the server after 'STRTCP' and 'STRHOSTSVR server(*ALL)' services were started from console. Can any one suggest me the solution? Also, only the display option is coming and the printer emulation option is not comming in the Communication screen now, whereas earlier I was able to create printer sessions also.
