res://c:\windows\system32\shdoclc.dll/dnserror.htm

:confused: The message on the subject line is the error I and many of my co-workers encounter when we try and access the internet. Now, it doesn't happen to everyone at the same time, and seems to jump from PC to PC. We are on a DSL and have DHCP and firewall. I wanted to know what the cause of this error would be? Also, what would be a fix to this issue? So far, the only known fix is to sit and wait and as mysteriously as it occurs, days later it stops occurring.

Any and all help would be greatly appreciated.

It's saying that it can't find the IP equivalent of the address you typed in. Hence the DNS error.htm

Check your firewall logs, your DNS configuration, and your utilization of your DSL for starters.

If that's too deep for you, call your DSL provider.

yeah i had this problem once on a windows 98 computer using IE, solution:
Switch to Netscape.
Oh and if it still is screwed up then re-install firewall.

I get the same message when I start up IE and hit the stop button before the initial page is loaded. As Korp said, it means you are having a problem looking it up in the DNS for somereason. Could be something as simple as a couple of packet errors whcih you cant to anything about, to a serious problem with your DNS server.

often this will fix if it's a random problem...only in 2k (xp and nt probably)


ipconfig /flushdns

I attempted this and it did not work on the Windows2k PC. I want to assume that it could be, but i hope not, a problem with the DNS server. Any other suggestions.

ok, first post here... Just trying to add to the possiblities, if my thinking is wrong flame away I don't claim to be an expert...

I have a couple theories... Do you use a hub or a switch to connect your computers to your dsl router (or firewall depending on how you physically set it up)? How many computers do you have networked? The reason I ask is you may be experiencing collisions on your network this will keep a lot of things from getting through. A switch will stop collisions a hub will not. Sometimes on my network this happens, but just restarting the firewall seems to clear things up. Hope it helps...

--have a "partial solution" this appears to me to be a problem involving "Internet Explorer" displaying a link "in a new frame" as opposed to just loading over the existing page...

I developed this problem recently and reloading IE6 and Win98 failed to resolve it...however...

when the new frame attempts to open ...and stalls...DO THIS:

1. CLICK ON THE "STOP" button to terminate the activity...then

2. HIT THE "RELOAD" button ...AND "BINGO" the frame/url you expected to come up WILL COME UP!

...this isn't exactly a "clean solution" but it does "get the job done"...if I uncover the "real solution"...I'll post here...

PS. I KNOW IS AN "IE" PROB...because I use "Opera 6" browser also...and it works fine in opening a link in a new window frame.

*** SOLUTION TO THIS PROBLEM: shdoclc.dll is apparently a "blank page" default when the "open url/link/frame in NEW WINDOW" fails to work...

what causes the problem: new software that alters your "oleaut32.dll" file....this is a win system file...has to do with opening linked files, etc...

I got this solution from: http://forums.32bit.com/showthread.php?threadid=14390 (scrolling down to the bottom of that page...wanted to give credit to the guy that solved this...anyway...

the solution:

1. hit your "Start buttom"...go to Help...type in "corrupted" ...(all your doing so far is to access the Windows Help guide)

2. a box will open up leading you to the procedure from restoring a "corrupt Windows" file of your "system CD" which you have in your CDrom drive.

3. basically you are typing in "oleaut32.dll" in the "restore a single file from your installion disk"

4. this will find the "oleaut32.dll" file on your system installation cd...and automatically overwrite it on the corrupted version on C:\windows\system ...

5. after you restart your computer ...the "open url/link/frame in "new window" will now work when using Internet Explorer!

Summary:

what causes the problem: software that when loaded inadvertantly corrupts your "oleaut32.dll" file (which resides in "C:\windows\system")

in my case the only two pieces of software I loaded recently which could have caused this problem were the "personal firewall program" ZoneAlarm and a "pop up stopping program"
PopUpStopper...

you can manually replace the corrupted version of "oleaut32.dll" in MSDOS...but I find it easier to use Windows automated system for replacing "corrupted files" that I outlined above....

by the way...prior to this I did reinstall Win98...but that didn't help....I suspect that the reinstallion of Win98 did not "overwrite the corrupted version of "oleaut32.dll" because a "newer - but corrupted version - of that file was on my hard-drive...and the reinstallion of the OS (operating system) did not give me the option of replacing/overwriting it with the "older original version of "oleaut32.dll" off my installation disk...

to make it simple...one way or another.... just get "oleaut32.dll" off your installation disk and overwrite it to C:\windows\system (or whatever location your "windows system" files are...

There are a couple questions:

You mention Firewall is it a hardware firewall or a software firewall installed on the system you are having problems with. IT is hardware on hte network it isn't a hardware problem with the system. It might be a hardware problem with the firewall that is dropping DNS resolution packets to your dns server (this is also assuming you are using an external DNS server and not running one internal to your network... there are a lot of assumtions here) It might be a problem with the external dns server. If it is siftware firewall on the machine then there might be your issue also.

When did this start to happen... all of a sudden or what was the change that caused this to take place. You state it is random and move from machine to machine. Wht type of router are you using? There might be a limitation with the number of hosts your router can support on an internet connection. It does not seem like it is specific to a mahcine configuration unless you just upgraded all of those machines recently (maybe a windows update??) since it moves around it sound like network capacity to me... and it might be router or firewall dropping DNS packet to UDP 53 (DNS resolution)

this seems to be a common problem with IE... I took down my firewall and the problem seems to not be there... but i know I'll have to do something other then this to cure the problem

i had the same problems as many descibed above - but was on dial up ntl connection.
have now switched to bt broadband - from the second i switched i haven't seem the message, and have never had a seconds problem......i tried many of the suggested solutions, none worked, but am now trouble free - no idea what the moral of the story is tho!!
