When the security equipment can’t connect the upgrading center, can through setting up LUS internal network upgrading server to realize the signature database upgrade server. After installed the windows 2003 server and LUS, enter http://server IP: 6020/sec in browser, found it can’t open LUS login interface. In windows server can’t find the “LUSpgsql” database service.
Through the website http://download.microsoft.com/download/7/9/8/798325b7-8993-4ef9-9148-8db9ff4187fc/vcredist_x86.exe download and install vcredist_x86.exe；and then uninstall the LUS, at last reinstall the LUS，LUS can operate normally。
This is due to the LUS server operation needs the supporting of VC2005 operation database, but windows 2003 hasn’t installed the database by default. To solve the problem, need to download vcredis_x86.exe to install.
