VPN Troubleshooting Tips

When businesses need secure Internet connections to and from their private networks, there's really no substitute for a VPN (virtual private network). Over the years, VPNs have achieved and maintained widespread popularity among the business community because they generally provide a reliable, effective way to secure sensitive information and prevent snooping.

That being said, network access and connection issues with VPNs are certainly not unheard of. With a number of systems and networks in the mix, determining where the VPN problem is coming from is often tricky work. To get your VPN issues resolved as quickly as possible, contact your IT support for help. If you are attempting to troubleshoot the problem yourself, there are a few relatively simple things you can do to narrow down the potential issues and - if nothing else - point your IT person in the right direction.

Identify the Affected Users

The first step to narrowing down the possibilities is to determine who exactly is having the problems. You probably won't find that you'll need to have your server reconfigured if there's only one person having VPN issues. If you are unfamiliar with this user's computer, keep in mind that they may have incorrect settings, viruses, or any other number of hardware or configuration issues that could be preventing them from accessing the network. If it's companywide, that's another story.

Test for Connectivity

Not every VPN problem is a connectivity problem. In some cases, users are actually able to connect through the VPN, but they are nevertheless unable to access files or other resources on the company network. If the users in question are in fact able to connect, you have at least established that connectivity is not the problem.

Check Network Permissions

If you can determine that there is a connectivity issue, you should be able to check the user directory and make sure that those users unable to connect have been given permission to log in remotely. Sometimes, all it takes is changing the permissions to fix a VPN problem. If users have permission but they still cannot connect, it may be that Network Access Protection is blocking the user because their computer is either not securely configured or has failed a health check.

Resolving VPN issues may very well require much more troubleshooting than the work outlined above, but following these steps should help you get closer to zeroing in on the cause of the problem.
