BPC 7.5 .NET server logon ID has no systemadmin rights

Hello Gurus,

When opening BPC 7.5 .NET server, I get the info "Your longon ID does not have systemadmin rights; some functionality is disabled". We do set up the logon ID in windows administrator group. We use BPC 7.5 SP07 with patch 1 on windows 2008 R2. Server diagonstic is OK. Does anyone have idea about this issue?

Thanks,

Haifeng
