Isa Error 995 Ssl
Contents |
Yosefi - MSFTSeptember 30, 20101 Share 0 0 When speaking with customers, we hear a lot of questions iis 995 around “unexpected” errors like “Failed Connection Error 995 Operation Aborted” error code 995 hulu and “Failed Connection Error 64 Net name Deleted” in the ISA/TMG logs. The main concern here
995 The I/o Operation Has Been Aborted Because Of Either A Thread Exit Or An Application Request
is always if these errors are real errors and how to prevent them. These errors occur most of the time when SSL traffic is involved.
Sc Win32 Status 64
First of all, if you see those errors: “Don’t Panic” 😉 These errors are expected in most scenarios, where you’re using ISA 200x or TMG without SSL Inspection. In this blog I want to provide some background about these errors, and why they are not an indication for an actual error in most cases. Another good article about these errors had been published by Thomas Detzner covering the connection of these with RPC/HTTP publishing (http://blogs.technet.com/b/isablog/archive/2007/06/25/rpc-over-http-logging-wildness.aspx ) Why 995 and 64? You may wonder why we’re not logging any HTTP Error codes but use error numbers like 995 or 64 instead. The answer to this question is quite simple: ISA/TMG are both running on Microsoft Windows, as you might have noticed J, where Error 995 and 64 are both standard error codes of the Win32 API, which are defined in the Winerror.h header file (http://msdn.microsoft.com/en-us/library/ms819773.aspx). This file contains the definitions for the standard error codes for Win32 API functions. But why doesn’t ISA 200x and TMG log the result codes defined in the HTTP RFC? This question directly leads to the cause of the failed connection attempt log entries, and is quite simple: “Because it can’t!” ISA 200x and TMG without HTTPSi can’t l

Access to the Web Proxy filter is denied. anonymous Web Proxy Filter The solution was found in: http://www.microsoft.com/technet/prodtechnol/isa/2004/plan/ts_client_rules.mspx in the section: Allow Anonymous Access to Specific Sites Problem: Some users cannot access the Internet. Cause: Require all users to authenticate is enabled on the network listening for Web requests from users, so all user requests must be authenticated. Requests from users unable to authenticate (for example users who are not members of a domain, or client computers configured as SecureNAT clients) are denied. Solution: Disable Require all users to authenticate. Instead, require authentication on access rules to sites to which you want to limit access. On sites for which you want to allow anonymous access, specify that rules should apply to All Users. I hope that thisaid to somebody Regards < Message edited by
