Hi, I have Microsoft SQL Server 2005 Express Edition with SP3, SP4, on Syperemicro Server, Intel Xeon E3-1220 v2 3.10GHz,8GB RAM and OS Microsoft Server 2008. We use Windows 7 desktop clients machine with enough CPU and RAM and arcgis software who is sync with MSSEE. But works very slowly. I am sure, the problem is not on the LAN or repeater. Maybe sync between arcgis and MSSEE. Does any one have an idea?
