Rebuild the client cache [witadmin]

You can force a rebuild of the cache on each client computer the next time it connects to a team project collection by using the witadmin rebuildcache command.

To prevent workspace errors from occurring during version control or build operations in Team Foundation, the data cache on client computers must be updated after certain maintenance operations. After you move, restore, rename, or fail over a data-tier or application-tier server, you must refresh the cache for tracking work items and users must refresh the version control cache on client computers.

The witadmin rebuildcache command invalidates cached data on all clients for a specified team project collection. This causes the cache for each client to be refreshed the next time the client connects to the project collection.

The following command invalidates the metadata cache for all clients that connect to DefaultCollection that is defined on the server that is named AdventureWorksServer. The client caches are updated the next time they connect to the project collection.

witadmin rebuildcache /collection:http://AdventureWorksServer:8080/tfs/DefaultCollection
