Your actual solution to the LAN problem may be replacing a network device, NIC, cable, or other physical component. If the problem is software, you may have to implement a software patch, reinstall the application or component or clean a virus infected file. If the problem is the user account, the user’s security settings or logon scripts may need to be adjusted.

Basically, there are two avenues exist for resolving software problems at the LAN connection. The first option is to reinstall the problem software, eliminating possibly corrupted files and ensuring that all required files are present. This is an excellent way to ensure that the second option – reconfiguring the software – works on the first try.

Many applications allow for a software switch that tells the installation program to disregard any existing configuration files, which is a good way to avoid being misled by the error and duplicating it yet again. If this option is not evident, then it is often better to remove the application before reinstalling it.
