QuickBooks Premier Professional 2013-Connectivity Issue on a Network

Computer #1 has the database file and has shared the folder.

Computer #2 has a drive mapped the the database file on Computer #1.


If Computer #1 has a user logged in, while in Multi User Mode, Computer #2 receives a communication error H202.

Computer #2 can access and open the database file in Single User Mode when the User on Computer #2 is not logged into the database.

Computer #2 logs into the database and tries changing to Multi User mode and receives a "Cannot access the database" error, while Computer #1 has no user logged in.

I have run the "quickbooks connectivity tool", and it did not help.


Any ideas?

Thanks.

Computer number 1 should be set for Host Multi User access, not Multi User Mode (they are different).

Close QB on Computer number 2, set Computer number 1 for Host Multi User Access and keep QB running.

Now open QB on Computer number 2 and with the big center Open button, navigate to the database. Computer number 2 will want to use Multi User Mode to access the file.

Make sure you are using Mapped Drives (NET USE) and not browsing for the folder.

I verified that Host Multi User access was enabled on Computer #1, and checked the box "Multi User Mode". But I am still getting the error "Cannot communicate with the company file"

Check firewalls between computers and that you are using mapped drives.

Make sure from Computer 2 you can use a file (Word / Excel) reliably on Computer 1.

Firewalls are OK. I am able to open office files on Computer#1, from computer#2

Should work. Try the following.

Disconnect computer 2.

On computer 1, close QB, delete the ND and DSN files from the company data file folder.  Open control panel, programs and features and do a QB Repair. When done restart.

Now open QB and be certain you are in Host Multi User Access mode.

Restart computer 2, delete the folder map, and then remake the folder map. Open QB and navigate to Computer 1 (do not use recent).
