Reasons
QuickBooks develops this hosting error while switching to multi-user mode if your 
PC is affected by the following conditions-
• QuickBooks hosting settings aren’t correct, and workstations are running in 
multi-user mode.
• The Network Descriptor file has been hit by corruption or a virus and can no 
longer be processed in the software.
• Windows Firewall does not allow QuickBooks to connect with other systems.
Solutions
The following methods are useful to troubleshoot this QuickBooks hosting error-
Solution 1- Ensure your QB hosting 
settings are correct
QuickBooks can be used to set up a multi-user network in which a server 
computer hosts the data file in multi-user mode, and all the remaining 
workstations use the file in single-user mode. This error blocks access to the 
company file or stops you from switching to multi-user mode if one or more 
workstations start running in multi-user mode. This causes a failure in the multi-
user network and generates the error you are experiencing. Configure the hosting 
settings using these steps-
1. Launch QuickBooks on the workstation that initially fell prey to this error.
2. Click File and select Utilities.
3. Tap Stop hosting multi-user access to use the single-user mode.
4. Go to all the workstations individually and switch them to single-user mode.
5. Run QuickBooks on the server computer and go to the Utilities option in the 
File menu.
6. Single-click the Host multi-user access option.
7. Restart all the systems and open the data file in multi-user mode on your 
server computer.
Use the next method if the error still creates problems in your QuickBooks.
Solution 2- Patch up the damaged 
Network Descriptor (.nd) file
This error can also stop you from setting up the multi-user network if the 
network descriptor file suffers from damage. You’ll need to rename the file, 
which helps it get recreated when you rerun QuickBooks on your system. Use the 
following steps-
1. Go to the QuickBooks folder using the file explorer.
2. Right-click the .nd file inside the QuickBooks folder and click Rename.
3. Add ‘.old’ at the end of the file name and save it.
4. Run QuickBooks Database Server Manager and go to the Scan Folders tab.
5. Choose the QuickBooks folder where you edited the file and tap Start Scan.
6. Wait for the scan to complete and open QuickBooks again.
