Hi, i have a server application and it runs on windows 2008 web server for backup. server application created by VC++ 6.0 ( uses _open, _write, open ssl,..) to receive the data and store in storage. application was fine when it was running in windows 2003 server. After moving to windows web 2008 , we are facing unpedictable issues. issues:file access to storage is slow, after running the server application( created using VC++ 6.0) more than 7 to 8 hours ( with backup), access( read, write, creating of files) to the storage is SLOW. How do we debugg this issue? is any one come accross this issue. Please provide your info. Thanks, Samson Petersingh

Hello, start with this really good article about the changes coming with Windows server 2008 network settings: http://msmvps.com/blogs/acefekay/archive/2009/08/20/tcp-chimney-and-rss-features-may-cause-slow-file-transfers-or-cause-connectivity-problems.aspxBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, Thanks for the info. I disabled the RSS & TCP Chimney, but still facing same issues. I am using windows 2008 web server for backup. Facing following issues: Issue 1: File creation on storage is slow after running the server application for some time. ex, when we tried to create a files in storage some time it takes more than 5 mins to create 5 to 10files. (but this issue is not often, currently we are fixing this issue by restarting the server app) Issue 2: some time we are not able to close the server application (created using vc++ 6). it takes lot of time to close/terminate the application. we tried via task manager, some time task manager is not closing the server app, and some time it shows the message as "unable to terminate, access denied message". Please provide your info. Regards, Samson Petersingh

Hello, does the server use more then one ip address and do you use other then the domain DNS servers on the NIC? For the VC++ created application you should maybe check within the MSDN forums for errors about using it on Windows server 2008, as there are some major changes in the OS architecture. http://social.msdn.microsoft.com/Forums/en/categories/ Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, we fixed this issue by changing the windows scheduler priority for the server app, by default windows scheduler is setting priority "low" for server application. Regards, Samson
