File not found

Dear Support,

After migrated to new server with OS Windows Server.  Some  links ibc2.wallezz.com cannot working due error in web.config. Example: When I click a "People" button on ibc.wallezz.com to http://ibc2.wallezz.com/users will show "404 - File or directory not found" as error message.

Its my web.config script:

<?xml version="1.0" encoding="UTF-8"?><configuration><system.webServer><security><requestFiltering><fileExtensions><remove fileExtension=".cs" /><remove fileExtension=".config" /><add fileExtension=".cs" allowed="true" /><add fileExtension=".config" allowed="true" /></fileExtensions></requestFiltering></security><rewrite><rules><rule name="Imported Rule 1" stopProcessing="true"><match url="^(.*)/$" ignoreCase="false" /><conditions><add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /></conditions><action type="Redirect" redirectType="Permanent" url="/{R:1}" /></rule><rule name="Exclude direct access to webroot/*"
                  stopProcessing="true"><match url="^webroot/(.*)$" ignoreCase="false" /><action type="None" /></rule><rule name="Rewrite routed access to assets(img, css, files, js, favicon)"
                  stopProcessing="true"><match url="^(storage|photo|theme|uploads|user|users|img|css|files|js|favicon.ico)(.*)$" /><action type="Rewrite" url="app/webroot/{R:1}{R:2}"
                      appendQueryString="false" /></rule><rule name="Rewrite routed access to plugin"
                  stopProcessing="true"><match url="^(API|Photo)(.*)$" /><action type="Rewrite" url="app/Plugin/{R:1}{R:2}"
                      appendQueryString="false" /></rule><rule name="Rewrite routed access to app folder"
                  stopProcessing="true"><match url="^(Lib|Vendor|View)(.*)$" /><action type="Rewrite" url="app/{R:1}{R:2}"
                      appendQueryString="false" /></rule><rule name="Main Rule" stopProcessing="true"><match url=".*" /><conditions logicalGrouping="MatchAll"><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /><add input="{REQUEST_URI}" matchType="Pattern" pattern="app/*" negate="true" /></conditions><action type="Rewrite" url="index.php" /></rule></rules></rewrite></system.webServer><system.webServer><rewrite></rewrite></system.webServer><system.web.extensions><scripting><webServices><jsonSerialization maxJsonLength="256000"/></webServices></scripting></system.web.extensions></configuration>

So how I can fix about that's web.config problem?
