NLB - Strange Time out issue with 2 WFEs MOSS 2007 ? RRS feed

  • Question

  • Hi,


     I am having a MOSS 2007 environment with the follo.

         

    Having  Two front end servers – each individual  Hyper-V  and   1 Index Server.

    These WFEs  are Virtual Servers with Windows 2008 64 bit OS.

    I configured the Windows Load balancing.

    In these 2 WFEs Two sites are deployed (One is Team site and One Publishing site) both are intranet sites.

     

    Now the issue I am facing here is:

     

    Assume that Tower1 and Tower2 are 2 different locations.

     We have a VLAN setup  Web sites are working in same VLAN[say Tower1] where Servers are set up without any issue.

    But Web sites are giving Time out issue when it is accessed from different location VLAN [Tower2], after some clicks or web site navigations and website will be up after few minutes.

    But the site  is working in different VLAN within in same location[Tower1 or Tower2] where server are set up

     

    When web site is timing out in different location VLAN [Tower2], web site is timing out in all the locations and we will not able to connect to front end servers remotely. But same time we are able to connect to hyper–V  and from there, able to connect to front end servers, web site is accessible from there without any issue
    Now the other strange issue we have analyzed here :

    We have created new SharePoint site, tried to access from different location VLAN  [Tower2], web site is functioning without any time out issue.

    But If we access using Load balancing URL, It is failing in different location VLAN [Tower2].

    The webs sites are functioning perfect as it is in single VLAN where all servers are set up. And also, New web site is working without load balancing in all loctions

     

    Does anybody know why this  is happening.We have double checked the SharePoint configuration didint find any suspicious thing.

     

    Thanks in advance

  • This issue has been resolved by disabling TCP/IP offloading in one of the frontend server

  • I meant is it Hyper-V setting or Hardware setting, i remeber that we has to turn off TCP Chimney for SQL Server timeouts which was a regisrty setting in OS.
