HTTP Error
"Dani" <dani[ at ]vetcontrol.com> 25.09.2006 21:06:47
Hello:

I have several replica sets with 10 replicas each one in a single machine
working since 1999.

Two weeks ago I got this error:

"3677 Failure to execute the HTTP request to start the internet synchronizer
or the internet server.
Use Replication Manager to configure internet synchronizer on the internet
server."

I have restored a backup of the system, even I have config another machine,
AND I STILL GOT THIS ERROR.

But this error appears sometimes, not always, most times but not always.

I have a Firewall and updated norton Antivir.


I'm triying config it with another web server but, I don't know if
replicacion works with anything different to IIS or PWS.

Anyone knows with other WEB SERVER could I use?

I'm woking with Windows NT 4 SP6, Internet Explorer 4 and Windows NT 4.0
Option Pack using IIS FTP and WEB services.

I don't have all hotfix instaled, because I don't know if it could be
dangerous for replicaction.
Is there any essential hotfix for replicaction?

thanks...
Dani dani[ at ]vetcontrol.com

This sounds like the likely culprit. Have you turned off the
Firewall to see if that fixes it?

There is the replication security hotfix:

http://support.microsoft.com/kb/320805

You should probably go through the Jet 4.0 FAQ to make sure it's not
covered there:

http://support.microsoft.com/?id=282977

and, of course, the two Jet 4.0 White Papers, the first on Jet, the
second on Internet Replication, both available for review here:

http://support.microsoft.com/?id=190766

As to the IIS question, I'm not aware that Internet replication can
work with any server other than IIS, but the documentation seems to
hint at the possibility, though offering no instructions for how to
do it except with IIS.

I wouldn't ever use Internet replication because of the fact that
all the documentation is oriented for IIS, and I don't consider IIS
usable in a production environment (i.e., never Internet-facing).

I still think the likely reason is that your Firewall or AV is now
blocking your web server from loading the synchronizer. You'd
certainly want it to block such things in general, as there are lots
of exploits out there that attempt to run executables via HTTP in
order to compromise your web server. The key is figuring out how to
allow it to run the synchronizer.

Thanks for your answer and the links but I'm working with:
Access 97 / Jet 3 / Replication Manager 3.5.

I got the error "3677 Failure to execute the HTTP..." only sometimes,
even with antivir and firewall stopped.

I don't know what happen (any virus perhaps) but the today the server
machine is really crazy.
After bootup it goes slow, sometimes sicronization works sometimes not,
sometimes I get 3677 error,
other I get "Internet is very slow" error. And when I try local
sincronization, directly with the master DB,
with some replicas, Windows Dr Watson says that access.exe cracks, even
sometimes cracks replication
manager exe.

I setting up this machine las friday (with NT 4 SP6 and without hotfix), now
I'm going to reconfig my old
machine and install every security update.

I'm afraid of install all updates becouse, for example with Internet
Explorer 5 Replicacion Manager 3.5 doesn't works, I think.

I working with one single machine, do you know if replication works fine
with one machine as FTP/WEB server and other as DB Replication Server?

And Replication Manager 3.5 over Windows 2000?

I have a big application made with Access 97 thats why I still working with
Replication Manager 3.5.


Thanks for your time.

Ah. You didn't say you were using Jet 3.5 -- I just assumed I'm the
only one still using the tried-and-true old-fashioned version! :)

Do you have WindowsUpdate automatically updating the server? This
could easily have downloaded and automatically installed some fix to
the server that has broken your Internet replication. I'd check the
event log for the day before things went haywire to see if there's
an indication of any patches having been installed, and if so, try
backing out all of them.

I assume you have looked at the Internet Replication White Paper:

http://support.microsoft.com/kb/181371

A PDF of this document is here (all on one line):

http://www.dfenton.com/DFA/Replication/Files/WhitePaper3_x_Internet
Replication.pdf

Then there are these KB troubleshooting articles:

Correct Syntax for Internet Synchronization Using DAO
http://support.microsoft.com/kb/170595/en-us

Internet Synchronization Fails with "Internet Is Very Slow" Error
http://support.microsoft.com/kb/222150

You might also want to browse through the Jet 4 Internet Replication
White Paper (all on one line, of course):

http://www.dfenton.com/DFA/Replication/Files/WhitePaper4_0_Internet
Replication.pdf

And the Jet 4.0 FAQ (again, all on one line):

http://www.dfenton.com/DFA/Replication/Files/FAQ4_0_JetReplication.
pdf

I find that the Jet 4 documents tend to have better and more
realistic explanations of the problems encountered with replication.

I've never had any problems with ReplMan with IE4, IE5 or IE6. I
don't know what relationship there would between IE and ReplMan.

I don't do Internet replication, but my reading suggests to me that
you can't have the replica that you synch with stored on a server
that is different from the FTP/HTTP server. You can certainly have
*other* replicas on a different machine, but the hub replica for an
Internet synch has to be on the FTP/HTTP server.

At least, that's the way all the instructions seem to me to read.

I run it on Win2K all the time.

No need to apologize for that!

Fist of all, thanks for all your tips.

<< Ah. You didn't say you were using Jet 3.5>
Ohh, I forget it, sorry.

<<Do you have WindowsUpdate automatically updating the server?>>
No, I think that you need IE 5 for this.

Today I have installed and anti-spy bot sofware and now system works better,
no every thing perfect, but much more better.
And I don't get HTTP error.
Probably some bots (that antivir don't detect) slow down web service.


<< I've never had any problems with ReplMan with IE4, IE5 or IE6. I

<<I run it on Win2K all the time.>>

Really, I'm not sure what's the problem, the Access 97 replication server is
here
before than me and people who config it said that there was a lot of
problems
with Access 97 replication over Windows 2000 + (IE 5) on the server machine.

I have develop a web version of this application with a new DB, that's why I
don't
waste too much time investigating, but if you said that it works fine over
Windows
2000, I must test it.

I also have Internet router config in single-machine (I don't know the word
in english)
becouse that people said that in multi-machine it doesn't works.
I also must test this.

Thanks again David.

Dani

This makes absolutely no sense, as IE is not used on the server end
for serving an Internet replication client. IIS is involved, but not
IE.

I've never had any ReplMan problems on any version of Windows,
whatever version of IE was installed.

But I don't do Internet replication, since I think it introduces too
many outside dependencies, and IIS is an unacceptable risk in a
production environment.
