info 5566

 

Error 5566 with InfoPath can be a result of different cases, but first of all check out the following:

 

• You call the web service at a site or site collection level (eg: h ttp://myserver/mysitecollection/_vti_bin/UserProfileService.asmx) 
• The user who is opening the form has access to the subject site collection
• Anonymous access is disabled through Central Admin
• In the web applications web.config file you have Proxy AutoDetect = false (on many cases I could leave this the default value true without a problem)
• If you have multiple web front ends, depending on your configuration you might have to add an entry to the hosts file (Eg: MyMOSS 127.0.0.1) so that InfoPath Form services calls the web service on the same server avoiding NLB..
• If you made the above change be sure that the address you add (MyMOSS) is the same name that you assign in IIS for that application. Basically it should be the same address clients are using.
