hi there,
I installed SAP on my virtual machine with XP on it. i installed SAP gui 720 on it and when trying to logon on it this error 127.0.0.1 pops up connection refused. the parameters are application server as "localhost" , instance number "00' and sid is NSP. I also load MS loop adapter and configure it with same ip address. I ping the IP address and it is working. then i checked my SAP MMC . so its not showing any syatem now. I saw my NSP with green light here before then it turned to blue and grey. Now its nothing showing there. Anybody help ?
