• Sharepoint database connection issue after upgrade to SQL Server 2008 R2

  - by Neil Hoff

  I took a backup of all our Sharepoint WSS 3.0 databases and restored them to a new Windows 2008 R2 server. The new SQL server has the same name and IP address as the old one. The only difference between the two is the new one has SQL 2008 R2 and the old one has SQL 2005. When I navigate to the sharepoint url I get this error: Cannot connect to the configuration database. I checked the logs at this location: "%commonprogramfiles%/Microsoft Shared/web server extensions/12/Logs" and found this error: System.Data.SqlClient.SqlException: Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. Any ideas?

• pfsense, active directory, local domain

  - by Dalton Conley

  First things first, I have no idea what I'm doing. Certainly not afraid to admit that.. but here is my network setup. I have 2 servers, one of them in a domain controller. Both are running windows server 2008. They have replicated directories. Each server is at a different location and has its own firewall for the network at that location. Both firewalls are using pfsense. Recently a firewall went down and my coworker reinstalled pfsense, and everything seems setup correctly. Again, I have no idea what I'm doing so I'm not sure. I have records from when the previous IT person had setup this network and the firewall settings are the same but those records could have been extremely old. Now, I have a domain name for my network.. we'll call it "mydomain.net". I use to be able to access this domain name and it would bring up the servers replicated drives(i.e. \\mydomain.net). Now I cannot. I can however access the servers individual host names on my network(i.e. \\server1 , \\server2). We didn't change anything on the server which is what makes me think its something to do with the firewall. I know this is probably a very general question and I don't have a lot of detail to add but could anyone give me some insight on to what could be causing this, or some debugging techniques I can apply to this? I'm a programmer, not a network administrator.

• Microsoft Office "Read-only" warning not appearing on Samba shares on Mac OS X Server

  - by bongo

  Hi, some of my users don't get the "read-only" warning (but "read-only" does appear on the title bar and the document is indeed opened read-only) when opening Office 2007 documents already opened by another user. We run the samba share off an XSan volume under Mac OS X 10.5.8 Server. Strict locking is on but oplocks are off (from Server Admin). At home, with a simple samba share in 10.6.3 server, it works correctly. Any ideas? or is this a 10.5.8 behavior?

• Exchange Server Contact Categories - How to Remove/Update All

  - by ben

  I've been tasked with cleaning up our companies contact database sitting on our Exchange Server 2003. The rub is this database of contacts has been neglected for the past couple of years and is now a bit messy. My issue is I have say a person named 'Bob Smith', and Bob is listed in multiple categories, 'Students' and 'Student'. I would really like to remove the 'Student' category from Bob and anyone else out there that has the same category. My question is, is there an easy way to edit the master category lists for contacts on the exchange server? I feel like I am missing something simple here since if I were playing with the categories that I use, to say organize email its very easy to do so, but I can't seem to find the proper way to do it for categories that are up on the server. I'm attempting to work through Outlook 2007 and Exchange 2003. Any insight would be very helpful as I really don't want to change 8000+ contacts by hand.

• Remove server from loadbalancer [on hold]

  - by Cris

  Our datacenter is load balancing the traffic to our weblogic servers based on an application deployed on each server called probe.ear It is a simple java app which is accessed by the loadbalancer and if it accessible it will redirect traffic to this server as well. When we want to remove one node from the loadbalancer we just stop the probe app and new traffic is not redirected to it BUT I am asking myself what about the current requests? The responses for the current requests are executed (completed). I did not had time to test (will do that first thing when go back to work) but on theoretical level for me it make sense to do so unless the loadbalancer has some special settings. Does my reasoning make sense to you? Just to make it clear since it was reported the question is not clear. Is there a way to configure a load balancer in a way that from a specific moment will not redirect traffic to a certain server without reseting the current requests ?

• Windows 2008 server smart card security module problem

  - by chris13work

  Hi, I've got a smart card reader and a server application using it as a security module. If I run it under DOS prompt, everything is fine. The server is running and clients can connect to it. I tried to install the server as window service and start it. The server starts but always gives back authentication error because it cannot call the smart card to do encryption. Then I tried to start it with task scheduler and set the trigger factor as "on startup". The server starts also but still cannot access the smart card reader. Then I tried remote desktop to the machine and run the server application under DOS prompt. Same error is returned. The situation is that the smart card reader only works under active console desktop environment. In the server application, WINSCARD API is used to access the smart card reader. Any suggestion so that we can access the smart card reader in running services? OS: Windows Server 2008 Smart Card Driver: Windows USB smart card Reader Smart Card API: WINSCARD

• Finding how a hacked server was hacked

  - by sixtyfootersdude

  I was just browsing through the site and found this question: My server's been hacked EMERGENCY. Basically the question says: My server has been hacked. What should I do? The best answer is excellent but it raised some questions in my mind. One of the steps suggested is to: Examine the 'attacked' systems to understand how the attacks succeeded in compromising your security. Make every effort to find out where the attacks "came from", so that you understand what problems you have and need to address to make your system safe in the future. I have done no system admin work so I have no idea how I would start doing this. What would be the first step? I know that you could look in the server log files but as an attacker the first thing that I would do would be errasing the log files. How would you "understand" how the attacks succeeded?

• SHH Tunnel for Remote Desktop via Intermediary Server

  - by Mihai Todor

  I've seen many examples of SSH tunnels on the nets, but I'm still having no luck with this. Here's the setup: Windows 7 PC in a private network, sitting behind a firewall, with PowerShellInsider SSH server set up and working fine. Public access Linux server, which has access to the PC. Windows 7 laptop, at home, from which I wish to do remote desktop on the PC. Now, here's what I've tried so far: SSH tunnel from my laptop to the Linux server: ssh -f my_user@LINUX_SERVER -L 6666:LINUX_SERVER_IP:6666 -N SSH to the Linux server where I've set up a tunnel to the PC: ssh -f 'PRIVATE_DOMAIN\my_user'@PC_NAME -L 6666:PC_IP:3389 -N Unfortunately, I must be doing something wrong, because it doesn't seem to work. Any ideas why or, at least, any suggestions on how can I try to debug this setup? At the moment, I have access to all 3 machines (non-root on Linux), so I can test whatever I want...

• Exchange Server 2007 Transport Errors -- SMTP Session Hangs

  - by devviedev

  Hello, I was doing some changes to the server (writing an Transport Agent). After trying to install it, I started to get some errors. Now, when connecting to the SMTP server the session hangs just after finishing the DATA section. I'm not sure what happened, I disabled my transport agent and uninstalled it, then restarted the server. The problem persists. In the Event Viewer, four of the same errors show up: Source: FSCTransportScanner Category: Scan Error Event ID: 5021 Description: Unable to retrieve internet monitor interface. What could have happened?

• Public DNS Server fails on Windows Amazon EC2

  - by Adroidist

  I have started a new Windows server instance on Amazon EC2. The security group has the following rules: Ports Protocol Source 22 tcp 0.0.0.0/0 80 tcp 0.0.0.0/0 443 tcp 0.0.0.0/0 3389 tcp 0.0.0.0/0 53 udp 0.0.0.0/0 -1 icmp 0.0.0.0/0 I am able to ping the public DNS server of the machine and i can connect to it using Windows Remote Desktop connection. However, when i put in my web browser the public DNS server, it fails to connect. Morever, I used filezilla and putty (and in both I loaded the private key .pem) but i receive connection timed out. I disabled the firewall on both my pc and the instance (which I entered using Remote desktop connection). Can you please tell me what I am missing?

• webm html5 videos lose connection with apache server

  - by Jizbo Jonez

  webm html5 videos that are played through a domain on my server sometimes lose connection. A video that is playing will start to buffer and then stop part of way through with that message "Video playback aborted due to a network error." displayed on the html5 video player. I am delivering the webm videos via a php script on an LAMP server. There doesn't seem to be any errors in the server logs. Is there any php.ini settings or httpd.conf that I need to set? I recently set 'Keep Alive" to "on" in httpd.conf could that be causing this?

• IIS Redirect a sub directory to an external URL

  - by Will Hancock

  Hi forgive my ignorance for I am a humble client side developer... I am a webapp made up of static HTML and JS. But I want to call an external service via AJAX, this causes some issues with CORS or Cross Domain policy on the browser. So I need to make a request to MY server http://dev.webapp.com/service So I want to redirect the /service on the server to http://externaldata.com/service And return the result. The Mac boys have acheived this in Apache with a proxy pass: ProxyPass /service http://externaldata.com/service Can anybody help with how to do this in IIS? I have found articles about ARRs and Reverse Proxy, terms that are alien and seem too complicated. As a humble webdev can I do this using IIS GUI?

• Website hosting from home - IIS6

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• Encrypt remote linux server

  - by Margaret Thorpe

  One of my customers has requested that their web server is encrypted to prevent offline attacks to highly sensitive data contained in a mysql database and also /var/log. I have full root access to the dedicated server at a popular host. I am considering 3 options - FDE - This would be ideal, but with only remote access (no console) I imagine this would be very complex. Xen - installing XEN and moving their server within a XEN virtual machine and encrypting the VM - which seems easier to do remotely. Parition - encrypt the non-static partitions where the sensitive data resides e.g. /var /home etc. What would be the simplist approach that satisfies the requirements?

• IIS crashes with unhandled exception in ASP.NET

  - by SnowCrash

  We had an issue recently with an unhandled exception in an ASP.NET C# application bringing down IIS and all application pools that it was hosting. IIS Manager was unable to restart or stop/start the service and I was unable start IIS again after killing w3wp.exe in the task manager. A system reboot restored IIS to a running state; as a primarily Linux admin, I generally consider an unplanned system reboot to resolve a software error to be an act of high heresy. Is there a way to "harden" IIS so that a faulting application does not affect anything but the request that exposes the fault? Some details on the server and application fault. IIS: 7.5 .NET: 4.0 Windows Server 2008 R2 Faulted on call to System.Net.Dns.Resolve() with a url pointing to a non-existant domain as the argument. (I'm aware that this method is deprecated but the point that a page code issue shouldn't bring down the server still stands) The exception generated was SocketException. The faulting module according to event viewer was KERNELBASE.dll The issue was resolved by wrapping the call in a try-catch, logging the exception and displaying some generic content on the page. I'm hoping that I missed something in the IIS config that would switch it to "production" mode or something.

• Coldfusion server VERY slow page loads

  - by Kevin

  I inherited a windows server 2003 coldfusion 7 server a few weeks ago. Today a network cable was unplugged by accident from the server. On plugging it back in, pages were NOT loading at all. Rather, we were receiving a generic coldfusion error page. After restarting IIS several times and coldfusion even more than that, we finally got pages to start loading. However, the loading is extremely slow (30+ seconds) on pages that used to load instantly. Loading through the local network (IE localhost/cfide/administrator) does nothing to help the load speed. I am not familiar with IIS or Coldfusion (We're in the process of migrating this to Linux/PHP), so this is all new territory to me. I'm hoping someone may have experienced this issue in the past and can help me solve it. I'm happy to provide any additional information that might be necessary....I'm just not sure what information you might need in order to help. Thanks for your time.

• Advice on new hardware firewall for a small company server-environment

  - by Mestika

  Hi everyone, My companies currently hardware firewall (an old ZyXEL ZyWALL firewall) and is indeed requiring an update to a new firewall. It is a small company with a similar small server-environment, so the need for a huge, complex and expensive solution isn’t there but a more “straight-forward” firewall, that can provide the necessary security to our systems and block unwanted elements from the core server and only accept access through our one server which is used as an “gateway” between the Internet and our internal network. I haven’t that much experience with hardware firewalls so I’m requesting any good advice and/or knowledge on which products will be suited for our specific need. If you need more information about the specific needs we require, please let me know and I’ll provide them to you. Sincerely - Mestika

• Websocket & HTTP proxy with server between two firewalls

  - by Dan

  I have a server ("A") running behind a firewall, which serves HTTP and websockets. I have no control over the firewall, but do have an external server ("B") to which the internal server can connect (note that the reverse connection from B to A is not possible due to the firewall). How can I set up some sort of proxy on B such that an Internet client ("C") can access the resources on A? I'd prefer something lightweight—even a Python program or an SSH tunnel (which I've tried without success)—rather than something more heavyweight but robust.

• creating cookbooks and roles with out chef-server

  I want to run: knife role create blah I use chef-solo and don't need knife to connect to a server. I just would like to run these commands for helping me prepopulate the files quickly. Everytime I run of these commands it attempts to connect to a server. This does not happen for knife cookbook create blah Double-ewe tee eff. Update: I've noticed this is the case for databags and environments as well. I've read elsewhere that knife is primarily intended for use with the chef-server API, but it seems ridiculous that something like this can't be done. It just needs to save the darn file.

• Unable to ping remote server Nagios

  - by williamsowen

  We've recently set up Nagios on one of our Amazon EC2 instances to act as a monitoring server to our other instances. nrpe was installed on our staging server stager and appears to be working fine: monitoring_server~: /usr/lib/nagios/plugins/check_nrpe -H xx.xx.xx.xx -p 5666 NRPE v2.12 The issue is - when viewing the remote server stager within the Nagios admin screen - it appears to be 'DOWN'. The check_ping command reveals: monitoring_server~: /usr/lib/nagios/plugins/check_ping -H 'xx.xx.xx.xx' -w 5000,100% -c 5000,100% -p 1 PING CRITICAL - Packet loss = 100%|rta=5000.000000ms;5000.000000;5000.000000;0.000000 pl=100%;100;100;0 Can anyone provide some direction on how to get this working?

• Windows VPN for remote site connection drawbacks

  - by Damo

  I'm looking for some thoughts on a particular way of setting up a estate of machines. We have a requirement to install machines into unmanned, remote locations. These machines will auto login and perform tasks controlled from a central server. In order to manage patching, AV, updates etc I want these machines to be joined to a dedicated domain for this estate. Some of the locations will only have 3G connectivity (via other hardware), others will be located on customer premises in internal networks. The central server (of ours) and the Domain Controller will be on a public WAN. I see two ways of facilitating this. Install a router at each location and have a site to site VPN between the remove device and the data centre where the servers are location Have the remote machine dial up and authenticate via a Windows VPN connection to the DC via RAS Option one is more costly to setup and has a higher operational cost. It also offers better diagnostics if the remote PC goes down. Option two works well but is solely dependent on the VPN connection been made before any communication can be made to the remote machine. In a simple test, I can got a Windows 7 machine to dial a VPN prior to authentication to a domain, then automatically login to the machine using domain credentials. If the VPN connection drops, it redials. I can also create a timed task to auto connect every hour in case of other issues. I'd like to know, why (if at all) is operating a remote network of devices which are located in various out of band locations in this way a bad idea? Consider 300-400 remote machines all at different sites. I'd rather have 400 VPN connections to a 2008 server than 400 routers, however I'd like to know other opinions on this.

• CentOS send mail with external SMTP server and without local daemons

  - by Vilx-

  I've got a little old server with CentOS 6.5 on it. The hardware is old and crappy, but enough for what it has to do. Which consists of SSH (+SFTP), Apache, PHP and MySQL. Still, I'm trying to cut away all that I can. One thing that it does not need to do is to be an SMTP server. There are no mailboxes on it and nobody will ever route mail through it. However I do want it to send me an email when something goes wrong. Also, the webpages will send emails from PHP. So that brings me to the question - can I set up the mail system in such a way that there isn't an expensive mailer daemon sitting in the background with queues and whatnotelse, but rather every email is directly and immediately delivered to an external SMTP server? And how do I go about it?
