Cracking the Code: A Case Study

Technology issues don’t always come with full system breakdowns or long network outages. It can be something as small and frustrating as not being able to log into your rent management system at the end of the month. 

This was the case for a property manager at a 55+ manufactured home community in Arkansas. When she tried to access Rent Manager, the software she relies on daily, she hit a wall: an error message, invalid credentials, and no ability to save her login info for future use. 

Left unresolved, a “small” issue like this can chip away at productivity and trust in the systems your team relies on to do their jobs effectively.

Especially at the end of the month, when most people are paying their rent. 

But with the right support, even the most stubborn tech issues have their fix. 

This case study highlights how Network Thinking Solutions stepped in to solve this issue, restore access, and keep daily operations running smoothly in time before the first of the month surge. 

The Challenge

When the property manager tried to log in to Rent Manager—the software she uses daily to manage residents, payments, and operations—she was stumped. An error message appeared, her credentials were invalid, and Windows Defender Credential Guard was blocking her saved login information from being used.

While she could still log in manually with her password, the system would not remember her credentials. That meant extra steps every time she needed access, and a risk of login errors or forgotten passwords getting in the way.

It may sound like a small glitch, but when your team relies on a platform like Rent Manager to keep operations running and tenants informed, even minor things like this can snowball into a much bigger issue. 

Time spent troubleshooting takes away from higher-priority tasks, and repeated login issues will inevitably lead to frustration, delays, and inefficiencies across the board.

This is when the property manager decided to reach out to Network Thinking Solutions, their managed IT service provider.

Calling Rent Manager Support

When the property manager called Seth at Network Thinking Solutions, the first step was the obvious one: reach out to Rent Manager support. If anyone could resolve a login issue with their own software, it had to be them.

But after walking through standard troubleshooting steps, Rent Manager’s support team hit a wall. They couldn’t replicate the issue or offer a fix that worked. The property manager was still stuck manually logging in, and the Credential Guard error wasn’t going away.

This wasn’t just frustrating, it was telling. If the vendor’s own support team couldn’t solve the problem, it was clear this wasn’t a run-of-the-mill login hiccup. It pointed to a deeper, system-level conflict that required a more specialized approach. 

And for a busy place like this manufactured home community , the clock was ticking.

The Network Thinking Solution

Once Seth from Network Thinking confirmed that the property manager’s login credentials were correct and the issue wasn’t user error, Seth rolled up his sleeves and dug deeper. Rent Manager support couldn’t resolve it, so he took matters into his own hands.

We turned to independent research, combing through technical forums and user threads for clues. It didn’t take long to uncover a pattern: other users had experienced the same Credential Guard issue when trying to save login credentials.

The important thing to remember here is that the fix wasn’t something you’d find in a basic help article. It required a registry-level change—the kind of technical work most teams don’t want to mess with.

Seth navigated to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceGuard

There, he created a new DWORD value called LsaCfgFlags and set it to 0.

The Results

After rebooting the system, the property manager was able to log in without a hitch. No more error messages, no more Credential Guard blocks. The best part? Her credentials were saved for future use, so she didn’t have to manually log in every time.

But the impact went beyond just fixing the issue.

By calling Network Thinking Solutions, the property manager avoided a long back-and-forth with third-party support and was able to get back up and running quickly. No more wasted time, no more login headaches. Just a smooth, efficient solution from a team that knows how to get things done.

It’s a small win that speaks volumes; this is what proactive, knowledgeable IT support looks like.

“The Registry Editor is a tool in Windows that lets you change some of the system’s behind-the-scenes settings. It can be helpful for fixing tricky issues or customizing how your computer works, but it’s not something to use lightly. Making the wrong changes can cause serious problems, so it’s important to be careful, do your research, and back things up before making any edit.” – Seth Doherty, Customer Support Technician at Network Thinking Solutions

And that’s time no busy property manager has to spare.

With deep technical expertise and a proactive approach, we cut through the confusion and delivered a solution that went beyond what standard vendor support could offer. 

The result? A smoother login process, less frustration for the property manager, and a more reliable system overall.
