Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

OK, but make sure you read up on RRAS before you enable it as it isn't trivial to configure. Also make sure your current hardware can forward GRE or IPSEC to your server (if you use NAT many can't). Yes, changing the firewall costs money, but it's a lot simpler.

comment Respond to HTTP OPTIONS with basic auth
You can disable WebDAV without appcmd, but obviously if you need WebDAV you're stuck. Even if you need WebDAV maybe you could still split the site into two separate sites, one with WebDAV enabled and one without. They could point to the same physical directory and you would use the WebDAV disabled site only when you don't want the HTTP OPTIONS verb to be processed. Other than that, your suggestion of an ISAPI filter is the only solution I can think of. Sorry :-(

comment Rsync or DFS-R for remote backup over slow links of Windows 2003 R2 SP2?
Was this over the LAN? "read error: connection reset by peer (104)" normally means the network connection between the two computers failed. I see it a lot when syncing through ADSL because ADSL lines do dropout fairly frequently. The other possible reason is that rsync at the remote end crashed, but I've never had that happen. If you restart the sync it will pick up from where it left off.

Aha, in that case see Matt Everson's post. You can set Performance Monitor to run a program when the CPU hits a speciifed level.

Ah, yes, I do need to update my article to include the new dll. I've edited my post to include more stuff about security as it's too big to fit in a comment.

I've used nLite many times to do this with a variety of different controllers. If it's not working you have the wrong drivers!

comment Why can't my Win2003 Server connect to my Win2008 PDC anymore after a minor network change ? (FRS problem?)
As pauska says, the initial error is cosmetic and can be ignored. See the edit for some more ideas, but I must admit I'm flailing around a bit now.

comment How to log all Internet traffic that goes through a server running Windows 2008?
I think SQUID is an excellent idea, though obviously we need to clarify whether the questioner wants all traffic or just web traffic. I too have used the Windows port of SQUID extensively and it's an excellent Windows web proxy, though admittedly configuring it can involve some head scratching. +1 from me.

Why was this voted down? The stored procedure sp_who2 is the first thing I'd run if I suspect excessive connections. Could you at least leave a comment saying why you marked my post down?

comment Help with simple networking setup
If you connect your web server to the main server, even if it's on a different NIC, you expose your server to any viruses running on the web server just as if you dropped it onto the LAN. If you're that serious about security you need a firewall between the two servers.

"The servers DO need see each other". Ah OK. I would just put the web server on the same subnet as everything else, but note that if someone managed to put Code Red on it you would allow the virus access to the rest of your network. If you really don't want this you need a firewall with a DMZ port. Then you can put in firewall rules to restrict the access from your web server in the DMZ to your LAN as well as to the Internet.

I suspect we have a problem with terminology. I'm using a VLAN in sense of en.wikipedia.org/wiki/Vlan. The VKLAN operates at layer 2 i.e. by MAC address and has no concept of IP address. My own router uses just this type of VLAN. I'd be happy to demo it.

comment How do I set up SMTP on Windows Server 2003 to forward all emails to a given address?
Oops. As splattne has spotted and as Evan Anderson says, the Windows SMTP server can't modify the mails. It can only relay them. However see my edit for a way of doing this.

comment Windows 2003 VPN behind standard router
The Draytek 2600s tend to give a slightly lower signal to noise than later models and consequently you get slightly slower speeds on ADSLMax. However if your line speed is OK they are, as you say, perfectly adequate and pretty cheap on eBay.

comment SQL Server Slow but CPU Normal
I'd be very surprised if there were any problems with the virtualised disks otherwise the event log would be full of disk errors. I have a basic disk tester at rattus/ratsauce/index.html#diskthrasher. It is very basic but should expose any serious disk performance problems. I think it's more likely something on your server is caning the disks. NB when the queue shows 100 it's usually >100. You can change the scale to see what it actuall is.

comment SQL Server Slow but CPU Normal
Oops, good point. If it's Hyper-V run perform in the VM. Because Hyper-V uses para-virtualization there is no "host" for resource use to show in. If it's VMWare Server then run Perfmon in both. If it's ESX then I guess you can only run PerfMon in the guest.

comment Forwarding hostheaders
SQUID listens on port 3128, so you'd need to configure inbound port 80 on your router to redirect to port 3128. Then you fiddle with the bloody complicated SQUID config file to configure the reverse relay. If you Google for "squid reverse proxy" or something similar you should find a howto.

OK how about using Alakdae's idea of VLANs. With Drayteks, and I'm sure other routers, you can put different ports on the embedded switch in different VLANs so packets cannot be switched between them. Both servers would see the Internet normally through the router but would have no access to each other.

>same IP subnet but separate VLANS The Draytek routers support VLANs on their embedded switch. That allows you to have two servers attached to the router, both of which can see the router and the Internet beyond it but cannot see each other even though they are in the same subnet. I expect this is what Alakdae meant. This seems a reasonable solution provided the two srevers don't need to transfer any data between them.
