title: TFS makes checkins as another user instead of my current user
body: <p>i have a public workspace for my user 'domain\user'</p>
  
  <p>when visual studio starts from my user, it automatically create another workspace for user 'domain\user1'</p>
  
  <p>all checkins a perfomed by 'domain\user1'</p>
  
  <p>both of users have full administrative permissions in TFS project collection</p>
  
  <p>result of <strong>TF WORKSPACES</strong> :</p>
  
  <pre><code>Collection: http://tfs-server:8080/tfs/collection1
  Workspace   Owner              Computer  Comment
  --------- --------------------- --------- ----------
  workspace1  domain\user1       computer1
  workspace1  domain\user        computer1
  </code></pre>
  
  <p>It seems that my workspace,by some unknow reasons, not visible to visual studio.</p>
  
  <p>When i set 'public(limited)' or 'private' for workspace with owner 'domain\user', VS give error during check-in:</p>

  <p>Does anyone help me to understand what is happening? Recently it works well, but it looks that something is going wrong..</p>
  
  <p>UPDATE: it is appears only on one computer 'computer1' and works fine on different mashine with same user login</p>
