3. Select "Application Tier" node
4. Check whether the "Notification URL" in the "Application Tier Summary" is configured with FQDN.
5. If not configure as expected, then configure the URL with FQDN by clicking on "Change URL" as follows 

Solution for Visual Studio IDE

2. Open IE.
3. Add *.<your TFS domain>.com to the local intranet settings

4. 

5. Open Visual Studio IDE to verify the missing image

Explanation:

TFS Web interface is not rendering the date field with respect to “daylight saving” which is causing the confusion between the date field displayed in web access and visual studio IDE. The TFS date fields populated with the date during “daylight saving” on and time as 23:00 are displayed as next day in Visual Studio IDE which is logical and expected.

Solution: 

Install latest "Daylight Saving Time (DST)" update for windows on your app tier(s).
