Hi Praveen,

Thank you so much for your article. We experienced similar situation that sometimes the clients received 403 Forbidden. We will try to give Read permission to the Bin directory.

My question is, how about the client is anonymous? In our SharePoint, we have enabled the Anonymous permission. Should we give read access to Everyone?

Thank you in advance

Hi Praveen,

I am getting HTTP 403 Forbidden for /_vti_bin/client.svc and all. .svc files under /_vti_bin. Initially I was not able to browse the /_vti_bin folder itself, however I was able to resolve it by enabling Directory Browsing. But I am still unable to browse client.svc. I took Failed Request Tracing log and below is the error:

MODULE_SET_RESPONSE_ERROR_STATUS

ModuleName : ManagedPipelineHandler

Notification : EXECUTE_REQUEST_HANDLER

HttpStatus : 403

HttpReason : Forbidden

HttpSubStatus : 0

ErrorCode : The operation completed successfully.

(0x0)

Any suggestions on how to resolve this...

Exactly what I needed.  Worked great, thanks!

Great Post, it helps me to fix my problem also!

This is great. My problem is resolved.

This is great. My problem is resolved.

Found similar behavior post-deploy of SP1, and used this reference to guide on the troubleshooting. Effectively found the lack of ACLs in the bin directory and solved it... thanks Praveen!

That worked for me too.

thanks mate. worked for me. one thing to keep in mind - it may not work if you add those permissions to folder which higher in the hierarchy.

[SOLVED] I had 403 on WFEs, but all worked fine from workstations. Solution: turn off the proxy on WFE.

HI All,

we have similar experience on few of the links resulting in 403 error . we have 4 WFE servers in SP Farm and the functionality is working perfectly fine on one of the servers whereas we are having issue on rest of 3 WFE servers.

we have tried the above recommendations but no luck yet.
enabled request tracing logs and getting the below warning in ISAPI module.

ModuleName IsapiModule
Notification 128
HttpStatus 403
HttpReason Forbidden
HttpSubStatus 0
ErrorCode 0
ConfigExceptionInfo  
Notification EXECUTE_REQUEST_HANDLER
ErrorCode The operation completed successfully. (0x0)
 
can you please recommend and share your viewpoints on priority.

You, sir are a boss! Thanks for this solution.
