In our SP2010 farm there are 2 WFE (WEB01 and WEB02) and 2APP servers. Between users and 2 WFEs there is a network load balancer.
Last week, by unknown reason, users are not able to browse Sharepoint pages thru one of WFE server (WEB01):
- Some users browse thru network load balance address he has half chance get "internet explorer cannot display the webpage" error.
- If browse thru
http://web01
user will 100% get "internet explorer cannot display the webpage" error. - Browse thru
http://web02
is alright. - Browse thru
http://web01:1234
orhttp://web02:1234
(the Central Admin page) is alright - Browse thru
http://web01:9999
orhttp://web02:9999
(another web application) is alright.
UPDATE: after further investigate, I think Round Robin Service Load Balancer Event may not be the direct cause.
Although user cannot browse http://web01
, he can direclty type in http://web01/Pages/Welcome.aspx
and browse the page. Hence, I think all the sites under http://web01
web application have problem to redirect users to the default HOME page. How can I fix it?
On Web01 server event log I found error:
SharePoint Web Services Round Robin Service Load Balancer Event: EndpointFailure Process Name: w3wp Process ID: 5911 AppDomain Name: /LM/W3SVC/123456789/ROOT-1-1234567879878978 AppDomain ID: 2 Service Application Uri: urn:schemas-microsoft-com:sharepoint:service:267adbb783e241d9a55a9916933680b1#authority=urn:uuid:5578be51c5254ac09f5cde1d0fd12f3f&authority=

How should I troubleshoot it?
