you do not mention if you have done a thorough scan for malware like using 'Spybot search and destroy' or 'Ewido'. It is possible that this may cause the problem with your .dll file. I would also try 'Winsockfix.exe', which is a registry restorer for internet connections.
I've been having a problem for the last 2 or so months and really need advice here.
I will not reveal the website, but it has a discussion forum that I regularily visited, and I now cannot access it. I thought my server had a problem but its been revealed that it is not them and i think its my pc.
I have windows xp service pack 2 and I just recently downloaded the updates - which stuffed my pc, that I had to get my boyfriend to fix for me - he reinstalled xp and now its running as it should but no access to the site page i wish to visit.
Whether its the forum or to contact the webhost, both reveal 'page cannot be found' - the properties say: res://c.\WINDOWS\system32\shdoclc.dll/dnserror.htm#http:// www. (website)
I can't seem to work out what its representing and what I can do to fix this problem without corrupting my system (as its already happened) - i dont think this file can be deleted either so I really don't know if this is the cause as to why I can't connect to this site.
Also, when I had emailed my server about the problem, they told me about the dns report and that the site had some errors - i have no email address of the webhost and the contact through the website, as mentioned before, also goes to 'page cannot be found' - i know problem lies within my pc cause i can access the forum at work, but I forget to email the webhost about the report.
oh, and prior to the email about the dns report, another techie suggested java update which i did and didnt solve anything.
Hope someone can help.
