title: Team Foundation Server Error - TFS206018 -add solution to source control
body: <p>Hi I have problem add solution to TFS 2010.  First I describe to you scenario.</p>
  
  <p>I installed TFS 2010 on Server 2008 - machine : Zeus.</p>
  
  <p>Then I created Team Project collection with  TFS Admin console.</p>
  
  <p>Name of Team Project collection is Pokec.sk.</p>
  
  <p>I am trying add VS solution from another machine : Ares.</p>
  
  <p>On machine Ares I have VS 2010.</p>
  
  <p>First I configure connection to TFS 2010. On connection from VS to TFS I used credential from machine Zeus.</p>
  
  <p>I used this credentials: zeus\administrator. Because I cant use credential from machine Ares.</p>
  
  <p>When I tried add solution to source control I got this error:</p>
  
  <p><a href="http://www.freeimagehosting.net/cnik5" rel="nofollow">http://www.freeimagehosting.net/cnik5</a></p>
  
  <p>I think that I am trying add solution to TFS under credentials ares\tom and this is not allowed.</p>
  
  <p>I tried edit Group Membership with TFS Admin console. But I dont know how can I add credentials from another location.</p>
  
  <p>I think it is security problem of TFS. Because Ares\tom is not in Group Membership of Pokec.sk.</p>
  
  <pre><code>Machine: Zeus  User: Zeus\Administrator  SW: TFS 2010
  
  Machine: Ares  User:Ares\tom             SW: VS 2010
  </code></pre>
  
  <p>how can I solve this?</p>
