On a Windows 2003 Server or Windows XP, TAC Vista is not able to locate the license server, even though everything seems to be set up correctly. You get the message "-15, 10 System Error: 10061 Winsock Connection Refused" when you try to open any TAC Vista software.
The TAC Vista software is looking for the license server on the PC defined, but the license server is running using the TCP/IP v6 address and the software doesn't support that on this operating system.
Uninstall TCP/IP version 6 and reboot the PC. Below is a description on how to do it.
For the IPv6 protocol for Windows XP with SP1 or later or Windows Server 2003, do the following:
- Log on to the computer with a user account that has privileges to change network configuration.
- Click Start, click Control Panel, and then double-click Network Connections.
- Right-click any local area connection, and then click Properties.
- Click Microsoft TCP/IP version 6 (for Windows XP with SP2 or later or Windows Server 2003) or Microsoft IPv6 Developer Edition (for Windows XP with SP1), and then click Uninstall.
- When prompted to confirm the removal of the Microsoft IPv6 Developer Edition or Microsoft TCP/IP version 6 protocol, click OK.
Alternately, from the Windows XP or Windows Server 2003 desktop, click Start, point to Programs, point to Accessories, and then click Command Prompt. At the command prompt, type netsh interface ipv6 uninstall.
To remove the IPv6 protocol for Windows XP with no service packs installed, do the following:
- Log on to the computer with a user account that has local administrator privileges.
- From the Windows XP desktop, click Start, point to Programs, point to Accessories, and then click Command Prompt.
- At the command prompt, type ipv6 uninstall.
