Remote Web Workplace - Some work others don't

My customers RWW only allows me (or anyone for that matter) to connect to the server and one of 8 desktops.  Not a Rights issue.  It worked to perfection until recently when the cutomer decided to change ISP's and install IP phones.  The entire IP structure changed and hosed up DNS.  Now RWW says it can't find most of the workstations.

4125 is forwarding.  I can maintain the server and 1 workstation on RWW.

I have a single NIC.

Any thoughts?

I've tried running the Internet and Email Connection Wizard, but it didn't help.  

Should I totally re-do DNS on SBS 2003?  How do I do that?

HELP!!

Did the installation of IP Phones entail installing a new router with DHCP running?  

Ideally you want to keep VOIP off of your SBS's subnet unless you are intimately familiar with how to configure routing such that these services can live together harmoniously.

How about posting a complete IPCONFIG /ALL from the server and a sample workstation.

Also, please navigate to the DNS Forward Lookup Zone for domain.local and use "Export List" on the Action menu to copy the entries found in that zone so that you can post those as well.

Yes, with the IP phone system came a new router (running DHCP), a new ISP, and nothing but trouble for me.  Worst of all, this could have been completely avoided if the customer, ISP and the IP phone provider consulted me. But that's a whole different story.

Let me know what you're thinking.  I'm not a big DNS guy, but I still think it's the issue because nothing else makes sense to me at this point.

Well, the problem is that you can't really be using your VOIP router for DHCP on your entire network unless you make sure that it follows the mandatory SBS networking configuration... this is generally not that easy to do, so it's best to leave DHCP in the hands of the SBS.

You would therefore not have the problem of having multiple DNS suffixes as well as having foreigh DNS servers listed for the workstation... both of which are no-no's in SBS-land.  This is really what tells you that you are going to have problems:  "Connection-specific DNS Suffix  . : IAD2300HOU.hou0"

Is there any way to get the VOIP off into it's own network?

There's always a way.  Right now the PC's are connected to the network through the IP phones. The new Cisco router hands out the IP addresses to the PC's and I assume to the phone system.  I don't have access to the router nor the phone system.

I can have the foreign DNS server addresses removed from DHCP on the router, but in doing so I would need to know what to do so the workstations can access the internet.  Also, I have other SBS servers acting as network DNS with the foreign DNS servers in DHCP and RWW works fine (This one's RWW also worked for several months before the new Router).  

What do think I should change in DNS and DHCP?  I'm at a loss.  I have other weird stuff going on too, like accessing mapped drives on workstations and seeing only some of the available folders and no files.  This seems to repair itself when the user synchonizes their folder until the next day.  I didn't have this problem before either.

All of the "weird" stuff happens because you haven't followed the "SBS-way" of configuring your network.  SBS is a specific use product and requires that it be deployed in a specific manner.  If you follow the recommended methods everything works... and it works well.

Removing the foreign DNS IPs will not cause the workstations to lose Internet access... that's because hopefully you entered these IPs as the forwarders when you ran the Configure Email and Internet Connection Wizard (CEICW -- which is linked as Connect to the Internet in the Server Management Console > Internet and Email).

If you didn't, then you can just rerun it... visual how-to is here:  http://sbsurl.com/ceicw

Jeff,

I went through all of the settings pointed out in the links.  Everything was set as it should be.  The only thing that looks out of order is the Reverse Lookup Zone in DNS does not contain a record for each computer on the network.  Firewall settings have to be correct or I wouldn't be able to RWW the server nor the lone workstation that I'm able to connect to.

I need to get more info on the IP Phones and work that angle.  Any other suggestions?  Other things I can test?

Thanks

If you don't have PTR records for each workstation then you won't have proper network communications... that's a rather important piece of the puzzle.  In fact, that's why you can't connect via RWW.

I would think that the VOIP system is stopping the Reverse Lookup Zone from being dynamically created.

Now that makes sense.  I'll check out the reverse lookup a little closer.  I'll let you know shortly.
