I have two Windows 7 machines in our office that lose connectivity to a network cluster (two servers clustered to host our main software application). They connect to our other servers (stand alone servers) just fine. Our servers are all 2003 R2. These two computers had been connecting to our cluster just fine the past 4-5 months, and now both cannot connect to launch the program linked to the cluster. The cluster still shows as mapped, and will eventually connect to the folders on there, but it takes forever to load them up. The other server foldrs/files that are mapped come right up with no issues. Any ideas?

Hi, First I want to know whether this problem occurs on another computer? How you connect to the servers? UNC or mapped drive? As a test, please check which server is contacted in cluste.Does this problem only occur on one of these server?If so, please check network setting of the problem server. In case this problem occurs on both these servers, please check whether the disk array was maintained recently. If not, I suspect this problem may be caused by cluster service, you may access Windows Server forum to check this problem: http://social.technet.microsoft.com/Forums/en-US/category/windowsserverPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
