After upgrading to Attaché v25, some users may experience significant slowness on workstations. Common symptoms include:
Long delays when entering the username or password in the login screen
Slow loading between screens
General performance lag on workstations while the server remains fast
This issue is commonly caused by IPv6 interfering with the connection between the workstation and the Attaché server. Disabling IPv6 on the affected workstation usually restores normal performance.
How to test the issue
Close Attaché completely on the affected workstation.
Open AttDBHostSettings.exe in Attache Application folder.
Open Command Prompt on the affected workstation and enter the following command:
ping HOSTNAME (Where HOSTNAME is your server's name shown after the @ symbol in the Attache Connection String).
For example, if the connection string displays @PC1, type ping PC1.
If the result displays an unusual IP address format (IPv6 address) as below, IPv6 is active and may be impacting communication between the workstation and the server.
How to Disable IPv6 on the Workstation
Open Control Panel on the workstation.
Select Network and Internet.
Select - Network and Sharing Center.
Select the connection they are using most likely Ethernet.
Select Properties The find and UNCHECK [Internet Protocol Version 6 (TCP/IPv6].
Click Ok.
Verify the Fix
Open Command Prompt and run the ping command again.
You should now see a normal IPv4 address as below:
Launch Attache again. The application should now operate at normal speed on the workstation.
