What Is System Error 5?by James Ford
System Error 5 problems may occur on a Windows computer when you attempt to use "NetView or "Net Time" commands and your system is unable to access the required files and information from the network. This can happen for a number of reasons.
The System Error 5 condition most commonly occurs because the Windows Vista User Account Control is not granting permission to local users. Other reasons can include: the clock on your system is not synchronized with the network time, you do not have permission to access the network, a firewall may be blocking access to the network, or an Active directory replication error has occurred.
Fixing a System Error 5 will depend on the cause. If the Windows Vista User Account Control is not granting permission to local users, editing a key in the Windows registry can resolve the error. If time synchronization is the problem, updating the system time to match the network time will eliminate the error. See the Resources section below for help with troubleshooting this error.
If you continue to experience System Error 5 issues, you should run a registry scan and a virus scan. This may correct the problem and will allow your system to run more efficiently.
