• Securing a Windows Server 2008 R2 Public Web Server

  - by Denny Ferrassoli

  I'm setting up a public web server: Windows Server 2008 R2, IIS7.5. Does anyone have a tutorial / walkthrough / tips on properly securing a public web server? I've seen a few tutorials but mostly focused on Windows Server 2003. What I've done so far: Created a specific user account for the website / app pool, Renamed Admin account, Installed FTPS, Configured firewall to block any non-public service (web / https), Configured firewall to allow access to management interfaces only from specific IP addresses (rdp, IIS management, ftp) Maybe a few other things but can't remember at the moment... ICMP is allowed... Should I disable all except ping? Port scan reveals only web and https ports. Any other suggestions? Thanks

• Prevent Outlook from automatically deleting meeting emails

  - by Wavy Crab

  I'm using Outlook Web Access to read my email. When I receive a meeting notice and acknowledge it, Outlook adds it to my calendar then deletes the email. Is there a way to disable Outlook automatically deleting the meeting email? There doesn't seem to be any way to configure this in Options - Messaging and Options - Calendar. Note that I'm using Outlook Web Access and not the desktop client. From the copyright date this appears to be Outlook 2007. Follow-up: Based on edusysadmin's comment I logged-in using IE8, which exposed a setting not available in Firefox - "Move out-of-date meeting requests and responses to the Deleted Items folder". However unchecking this box doesn't seem to impact the auto-delete behavior. Follow-up 2: Keep in mind I am using Outlook Web Access via a web browser. I do not have the thick client Outlook installed.

• Why Is Web Sharing Broken on My Mac?

  - by Sam Murray-Sutton

  Background: I use my Mac for web development, running copies of web sites locally. I recently installed the Snow Leopard update, which to all intents and purposes seems to have gone fine, except... What's not working? Web-sharing; more specifically I can't turn it on via preferences. The preference pane just hangs when I try to. So Apache doesn't start on reboot. I can start Apache by hand, but I don't know enough to either setup apache to start with the computer, or to properly fix web sharing. Further details My Apache error log shows nothing on when the system boots up (as I would expect). This is the error message when I try to start web sharing from the sharing preference pane. 28/09/2009 10:58:05 System Preferences[834] setInetDServiceEnabled failed with 1 for org.apache.httpd Here's the messages given when I start apache from the command line. [Mon Sep 28 10:35:53 2009] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Mon Sep 28 10:35:54 2009] [warn] mod_bonjour: Skipping user 'sams' - index file /Users/sams/Sites/index.html has zero length.

Any help would be greatly appreciated. UPDATE I have added an answer of my own below - I was able to solve it thanks to being pointed in the right direction by the comments below, so thanks very much. But I'm still not totally clear as to what caused the problem or how my solution addressed it, so I'm leaving the question open for now.

• Unable to map to web folder using WebDAV client on Windows Server 2008 R2

  - by user74989

  I have a client running Windows Server 2008 R2 on several servers. One of the servers is also running SharePoint 3.0 and my client has created a web folder to map to. I can map to the web folder from all Server 2008 R2 boxes that have the WebDAV client (part of Desktop Experience feature) installed, except for the server the folder resides on. When I attempt to map to the web folder on the server which the folder resides, I am repeatedly prompted to enter my credentials. I am using the same account that I used to map the web folder on the other servers. I have also tried mapping from the command line and receive 'Access Denied' What may be causing the problem? I would think that if I can map to the drive from one server, I should be able to map the drive from the rest as long as the WebDAV client is installed, especially on the server where the folder is located.

• Is there a web-based VNC client that I can use from my own web site? [closed]

  - by Eliot Solomon

  I'm interested in being able to control one of my computers remotely, without having to download and install a bunch of software on every machine I want to access my computer from. Is there a VNC client or RDP software that can be embedded in a web page? I realize this seems like it might be a web application based question, but the web application portion would only end up being one small portion of the whole solution. Would VNC really be the way to go for this?

• How to Host Multiple Domains / Web Sites on one IIS6 Server

  - by Josh Stodola

  I currently have an IIS6 server that hosts one web site/domain. I am developing another web site (completely separate) that I want to host on this same server. Both domains were purchased from GoDaddy. I believe I will need a server-side ISAPI rewrite filter to internally route the incoming requests based on the domain name. I plan to use Ionic's ISAPI Rewrite Filter to do this because it is free. I know how to install the ISAPI filter and apply it to a web site in IIS, but I have no clue how I am going to route the incoming requests correctly (based on the domain). Also, I don't know if it is wise to setup multiple "Web Sites" or "Virtual Directories". I am thinking that this will depend on how the configured. How should I go about getting this accomplished?

• Failed to generate a user instance of SQL Server

  - by Goondocks

  I'm using Windows 7 Beta and trying to install a web application locally. This web site uses Microsoft SQL Server 2005 Express (SQLEXPRESS) and a MDB file in the web site's ~/App_Data folder. I was instructed to configure IIS7 to use Classic .NET AppPool for this web application. Each time the web site loads, I receive the following error: There was an error trying to connect to the Database Server: Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. The Internet is packed with articles written on this subject. The prevailing wisdom seems to be: Configure the SQL Express Service to use the Local System account. Delete the following directory: C:\Users\username\AppData\Microsoft\Microsoft SQL Server Data\SQLEXPRESS Neither of these fixes have made any impact. I have tinkered with permissions and settings for hours to no avail. Can anyone suggest a fix or help me understand how to get more detailed information about the problem.

• A clear understanding about Mozilla Firefox web applications

  - by Girish Mony

  I have seen lately a concept of installing open web applications in Firefox and Google Chrome just like extensions here . While the site says it as a installable websites. It looks very similar to bookmarks to me. When you click either bookmarks or this installed applications, it opens new tab and the site or application can be viewed. My question is what is the main difference between normal web application like Gmail, or Super user or Facebook and these installable websites? Also what is the advantage in using this installable web apps from normal web applications which we can access by entering url in the browser address bar? I hope this is the right place to post this question. If not please guide me accordingly.

• Reputable web based ssh client? [closed]

  - by Doug T.

  I'm connected to a coffee shop's wireless network right now, and I suspected I'd be able to use my laptop and ssh somewhere. Unlucky me they seem to be blocking everything but web traffic (my testing seems to show everything but port 80 is working, can't ping, ftp, etc). I googled "web based ssh clients" however I have reservations about entering my login credentials on any Joe Schmoe's web app. I was wondering if anyone has had any experience with any reputable web based ssh clients? If so could you please point me at one that I could trust?

  Is there an open-source web app for viewing .ics calendars? I have a server running the open source CalDAV server "DAViCal" to share calendars between co-workers. I (the admin) add/delete the calendars by configuring my Mac OS X iCal application, but I want to also host a web app that displays a human-readable calendar, so without any configuration my coworkers can visit a web page and see the calendar.

• Amazon EBS for web site files

  - by MattB

  I'm new to the Amazon EC2/EBS system. I'm trying to figure out the "best practice" for hosting a web application (php, ASP.NET, etc.). The way I see it, I have 2 options: Have the instance hold my web files - Don't need to worry about attaching volume's etc.? Have EBS volume hold my web files - Easily update with new code without needing to recreate the AMI for new updates? How do others handle this?

• Some URLs fail to load on Windows web portal

  - by jpolache

  I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

• Rails web app authenticated with windows

  - by deostroll

  Is it possible for a rails web application to make use of the windows authentication features in its code. I am looking at being able to obtain the user's login name and domain in the application. But there is a catch. This particular web application runs off an apache web server hosted on a linux machine which is kind of networked to other windows machines. Is all of this possible?

• iis 7.5 - WFF and ARR farm management

  - by smackaysmith

  We have two test web farms (IIS 7.5). The Florida web farm has two ARR servers and two content servers. The ARR servers have WFF and NLB installed. The ARR setup uses a shared config located on a file share. The content servers do not have WFF installed. There is one web farm, and it's managed on an ARR server. The Illinois web farm also has two ARR servers and two content servers. ARR servers have WFF and NLB installed, and they use a shared config located on a share. One of the content servers has WFF installed, which makes it the controller; it's also the primary content server. Apparently, Illinois isn't properly configured. From what we've pieced together from various IIS.net articles and this post (http://ruslany.net/2010/07/web-farm-framework-2-0-overview/), the controller should be one of the ARR servers (like our Florida setup). The thing is Florida's controller doesn't have a Primary server nor can you set one of the content servers as Primary. It doesn't have the management piece showing the Trace messages when you click the Servers node (from iis console, Server Farms/FLFarm/Servers http://ruslany.net/wp-content/uploads/2010/07/WebFarm8.png). That management piece does exist in the Illinois farm, but that's a bad configuration. What are we missing that our Florida configuration doesn't have the Primary and Secondary content servers, and the management piece? I have looked for IIS role differences, but there are none.

• Web interface to allow users to change their Active Directory password

  - by csexton

  I have a few web applications that use Active Directory to authenticate. What I would like to be able to do is provide a simple web page that would allow users to update their AD password. This wasn't a problem when the majority of the users had windows machines that connected to this AD server (and could ctrl-alt-del to change the password), but we are moving away from that and the AD server is mostly for web apps. Is there a simple solution for this, or am I looking at the big LDAP managers?

• How to setup a web server with remote SMTP

  - by IP

  I have 2 severs, both running server 2008 (R2) One is the web server, one is running as a mail server. The setup I want is that any mail sent from apps (php, asp and asp.net) on the web server are sending mail through the mail server's SMTP server...but this seems to be proving trickier than i'd hoped. The mail server is running MailEnable, and the web server IIS7 (maybe 7.5) What i don't want is to setup an open relay SMTP server on the web server, as this is going to be open to abuse (even if I just allow relay from local address). the problem is, there doesn't appear to be a way to specify credentials in php so if I point it at the mail server, then the mail server has to be set as an open relay, which is almost worse. Any ideas how I should be doing this?

• Windows Server Shares web interface?

  - by Lazlow

  At work and home, I use Server 2003 with Windows Shares. We also have a couple of Netgear ReadyNAS appliances at work, managed via the web interface. Is there a built-in Web Interface for managing Shares, or a free one available - for use in Server 2003 (or 2008)? The reason I ask is that it would be good to manage the Shares via the Web, rather then RDP onto the Server each time - and would allow other users to treat it as a NAS.

• how to go about scaling a web-application ?

  - by phoenix24

  for someone whoes been primarily a web-application developer, and know not much about scaling/scalability techniques. I'll start by stating my application is written in Python, using Django; a fairly standard setup. I currently use Apache 2.2 for my webserver, and MySql for my database server; both running on the same vps server. Up until now, it was basically a prototype and merely 15-30 concurrent users at any given time; so I had no issues, but now since we'll be adding more users we'll have severe performance issues. So my question is how do i go about scaling my web-application? and my plan is as follows. Now I have just one vps server running, apache + mysql. Next, I plan to add another vps server, to run only MySql; so i'll have one web-server and one db server. Next, I'll add Memcache to the webserver for caching data; and taking some load off mysql. Next, another web-server for serving all the static content; Next, a vps server for load-balancing (nginx/varnish) behind which would be my two web-servers and then db-server. Does that sound like a workable strategy, please guide me around here.

  I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser.

However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?
