Whether your team is in-office or remote, it helps you safely share your QuickBooks file without risking data loss, sync errors, or permission conflicts.
Add As A Preferred“Hey, this is Malcolm Lovelace. I’ve been using QuickBooks Desktop Enterprise 2024 to manage our business finances from the main office computer without much trouble. Recently, I needed to give remote access to a second PC so one of our team members could help out with bookkeeping from home.
I tried setting it up myself, but things quickly got complicated. The second PC kept getting errors like ‘Can’t locate the company file’ or ‘QuickBooks needs to be in multi-user mode.’ I wasn’t sure if it was a firewall issue, a problem with the Database Server Manager, or something else entirely. I did install QuickBooks on the second PC and tried using the same company file over the network, but it either wouldn’t open or said the file was already in use.
I’m now wondering—what’s the right way to securely grant access to a second computer in QuickBooks Desktop Enterprise 2024? Should I be using Remote Desktop, setting up a dedicated server, or adjusting file-sharing and hosting settings within QuickBooks? I want to make sure we’re not compromising our data or causing sync issues. What’s the fastest and safest way to get this resolved right now?”
Hi Malcolm Lovelace, you might see messages like “Can’t locate the company file,” “QuickBooks needs to be in multi-user mode,” or “The file is already in use” if QuickBooks Desktop Enterprise isn’t set up for shared or remote access.
In most cases, the fix is straightforward:
You’ve already installed QuickBooks on the second PC and tried opening the shared file, so the remaining obstacles are likely network rules, hosting conflicts, or misconfigured permissions.
Note: QuickBooks Desktop has specific issues, while QuickBooks Online is cloud-based and requires no hosting or server. Team members can easily sign in from any device to collaborate in real-time.
Let’s walk through why this happens and how to apply the right method, depending on whether your team works from the same location or remotely.
Yes. QuickBooks Desktop stores your company file on a local computer or server rather than in a browser, but that does not lock you to one machine. With multi‑user mode enabled and the server mapped as a network drive, multiple users can work simultaneously. You can also access QuickBooks Desktop Enterprise remotely using remote desktop services or remote access tools. Beyond that, you can connect through cloud hosting, Windows Remote Desktop Services (RDS), or Virtual Desktop Infrastructure (VDI) — each option differing in cost, setup complexity, scalability, and IT support needs.
These are common setup issues when trying to enable access from a second computer:
| Error Message | Likely Cause |
|---|---|
| “Can’t locate the company file” | ▪ File path was not shared correctly ▪ Permissions not granted ▪ Firewall blocking access |
| “QuickBooks needs to be in multi-user mode” | ▪ Multi-user mode disabled ▪ The Database Server Manager is not running |
| “File already in use” | ▪ File opened in single-user mode ▪ Improper hosting settings |
Accessing a remote work-from-home computer over a basic network isn’t ideal without a VPN or remote server. You have two main options based on how frequently the remote user needs access:
Best if your team member only needs access occasionally, and you want full control from your main office PC.
The team member connects to the host PC to operate QuickBooks remotely, ending the session without transferring or sharing data externally.
In cases where the remote user requires direct file access over a network, this method is effective, provided it is properly configured.
On the main office computer (host):
On the second PC:
Best if your team needs secure, anytime access from multiple locations without managing servers yourself.

QuickBooks Desktop Enterprise 24.0 can be accessed remotely in multiple secure ways, depending on your team’s needs. For occasional remote work, remote desktop software is the fastest and safest option, keeping data on the host PC without complex setup. For ongoing collaboration, multi‑user mode with Database Server Manager, combined with proper network or VPN configuration, ensures simultaneous access to the company file. Advanced setups like cloud hosting, Windows RDS, or VDI provide scalability and enterprise‑grade control, but require more IT support.
By choosing the right method and ensuring firewall ports, permissions, and hosting settings are correctly configured you can grant remote access without risking data integrity or performance.
Yes, You can access it through multi‑user mode, remote desktop services, or QuickBooks remote access tools.
Yes. The number of users depends on your QuickBooks license. QuickBooks Desktop Enterprise supports up to 40 users, while Pro and Premier typically support up to 3 and 5 users, respectively.
Immediately re-establish the remote session to avoid file lock errors. If the company file remains open in QuickBooks, restart QuickBooks on the host PC and verify no one else is accessing the file before reconnecting.
Open the QuickBooks Database Server Manager on the host PC and check the “Monitored Drives” section. If your company file folder is listed and showing “Running,” it’s set up correctly. You can also scan the folder manually if needed.
