如何更换TFS 2018许可证密钥？新手管理员MTM连接问题求助

Hey there! Let’s get this sorted so you can fix that MTM connection issue once and for all. Here’s a straightforward, step-by-step guide tailored for TFS 2018:

Step 1: Fire up the TFS Administration Console #

• Log into your TFS server using an account with full administrator permissions (either local server admin or a member of the TFS Administrators group).
• Open the Team Foundation Server Administration Console—you’ll find it in the Start Menu under Microsoft Team Foundation Server 2018, or you can run TfsAdminConsole.exe directly from C:\Program Files\Microsoft Team Foundation Server 15.0\Tools.

Step 2: Navigate to License Management #

• In the left sidebar of the console, expand your server’s node (it’ll show your server name) and select Licensing.
• This page will display your current license details, including the existing product key and any expiration info.

Step 3: Input Your New Valid License Key #

• Click the Change License button (it’s prominently placed on the right side of the Licensing page).
• In the pop-up window, paste or type your new valid license key into the input field.
• Hit Verify to confirm the key is valid for TFS 2018. If you get an error, double-check for typos or make sure the key is specifically meant for TFS 2018 (not a later Azure DevOps Server version).

Step 4: Apply the License and Restart Services #

• Once the key is verified successfully, click OK to apply the new license.
• To ensure the changes take full effect, restart all Team Foundation Server services:
  • Open the Services app (run services.msc from the Run dialog), find all services starting with "Team Foundation Server", right-click each, and select Restart.

Step 5: Test MTM Connection #

• Head back to your MTM client and try connecting to TFS again. The license-related connection block should be gone if everything was applied correctly.

A quick heads-up: Double-check that your license is explicitly for TFS 2018—later versions (like Azure DevOps Server) use different keys and won’t work here. If you still hit snags, confirm your MTM user account has the necessary permissions to access TFS.
