  • Referencing SQL Server 2008 R2 SMO from Visual Studio 2010

    - by user69508
    Hello. We read a number of things about referencing SQL Server SMO from Visual Studio but still don't have the definite answers we need. So, here it goes... A number of years ago we created a C# application using Visual Studio 2005 and SQL Server 2005. In that application, we added .NET references to a number of SQL Server SMO objects, and everything worked fine. Those references were: Microsoft.SqlServer.ConnectionInfo GAC 9.0.242.0 Microsoft.SqlServer.Smo GAC 9.0.242.0 Microsoft.SqlServer.SqlEnum GAC 9.0.242.0 We have now migrated to Visual Studio 2010 and SQL Server 2008 R2. However, when we try to reference those same SMO objects for SQL Server 2008 R2, they don't appear in the .NET references tab. We're wanting to reference the SQL Server 2008 R2 version of those same SMO assemblies for our upgraded C# application. On our development machines, we have SQL Server 2008 R2 Developer installed with all options, including the SDK such that the assemblies are found in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, my first questions are: Are we supposed to do file references to the SMO assemblies instead of .NET references in Visual Studio 2010 w/ SQL Server 2008 R2? Or, is there some problem with our development machines such that the SMO assemblies are not appearing in the .NET references tab? Next, our production machines will have SQL Server 2008 R2 Workgroup installed with the client tools option selected, thus providing those same SMO assemblies in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, the next questions are: When we release to production, are we supposed to redistribute the SMO assemblies with our application? Or, will our application work on the production servers without redistributing the SMO assemblies (since the client tools/SMO assemblies have been installed)? What else????? Thanks for the help!

  • Nginx - Enable PHP for all hosts

    - by F21
    I am currently testing out nginx and have set up some virtual hosts by putting configurations for each virtual host in its own file in a folder called sites-enabled. I then ask nginx to load all those config files using: include C:/nginx/sites-enabled/*.conf; This is my current config: http { server_names_hash_bucket_size 64; include mime.types; include C:/nginx/sites-enabled/*.conf; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; root C:/www-root; #charset koi8-r; #access_log logs/host.access.log main; location / { index index.html index.htm index.php; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server{ server_name localhost; } } And this is one of the configs for a virtual host: server { server_name testsubdomain.testdomain.com root C:/www-root/testsubdomain.testdomain.com; } The problem is that for testsubdomain.testdomain.com, I cannot get php scripts to run unless I have defined a location block with fastcgi parameters for it. What I would like to do is to be able to enable PHP for all hosted sites on this server (without having to add a PHP location block with fastcgi parameters) for maintainability. This is so that if I need to change any fastcgi values for PHP, I can just change it in 1 location. Is this something that's possible for nginx? If so, how can this be done?

  • Cisco ASA5505 won't sync with NTP

    - by Martijn Heemels
    Today I noticed that the clock my Cisco ASA 5505 firewall was running about 15 minutes late, which surprised me since I've set up the NTP client. My two NTP servers 10.10.0.1 and 10.10.0.2 are virtualized Windows Server 2008 R2 domain controllers, and both have the correct time. As shown below, the ASA knows about the two servers, can ping them and seems to poll them periodically, so I suppose it can reach them both. The ASA claims its time source is NTP, however the clock is unsynchronized. Neither host is marked as synced. Result of the command: "ping 10.10.0.1" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms Result of the command: "sh ntp ass" address ref clock st when poll reach delay offset disp ~10.10.0.1 .LOCL. 1 78 1024 377 0.5 643.69 17.0 ~10.10.0.2 10.10.0.1 2 190 1024 377 0.9 655.91 58.4 * master (synced), # master (unsynced), + selected, - candidate, ~ configured Result of the command: "sh ntp stat" Clock is unsynchronized, stratum 16, no reference clock nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6 reference time is 00000000.00000000 (07:28:16.000 CEST Thu Feb 7 2036) clock offset is 0.0000 msec, root delay is 0.00 msec root dispersion is 0.00 msec, peer dispersion is 0.00 msec Result of the command: "sh clock detail" 10:33:23.769 CEDT Tue Jun 26 2012 Time source is NTP UTC time is: 08:33:23 UTC Tue Jun 26 2012 Summer time starts 02:00:00 CEST Sun Mar 25 2012 Summer time ends 03:00:00 CEDT Sun Oct 28 2012 I've tried the basic steps of manually setting the time and removing and adding the timeservers, to no avail. My ASA's ntp config is simply: ntp server 10.10.0.1 ntp server 10.10.0.2 Do I need to enable authentication to use a Windows NTP server? Any thoughts?

  • Query Execution Failed in Reporting Services reports

    - by Chris Herring
    I have some reporting services reports that talk to Analysis Services and at times they fail with the following error: An error occurred during client rendering. An error has occurred during report processing. Query execution failed for dataset 'AccountManagerAccountManager'. The connection cannot be used while an XmlReader object is open. This occurs sometimes when I change selections in the filter. It also occurs when the machine has been under heavy load and then will consistently error until SSAS is restarted.

  • Using UDF on a USB flash drive

    - by CesarB
    After failing to copy a file bigger than 4G to my 8G USB flash drive, I formatted it as ext3. While this is working fine for me so far, it will cause problems if I want to use it to copy files to someone which does not use Linux. I am thinking of formatting it as UDF instead, which I hope would allow it to be read (and possibly even written) on the three most popular operating systems (Windows, MacOS, and Linux), without having to install any extra drivers. However, from what I found on the web already, there seem to be several small gotchas related to which parameters are used to create the filesystem, which can reduce the compability (but most of the pages I found are about optical media, not USB flash drives). I would like to know: Which utility should I use to create the filesystem? (So far I have found mkudffs and genisoimage, and mkudffs seems the best option.) Which parameters should I use with the chosen utility for maximum compability? How compatible with the most common versions of these three operating systems UDF actually is? Is using UDF actually the best idea? Is there another filesystem which would have better compatibility, with no problematic restrictions like the FAT32 4G file size limit, and without having to install special drivers in every single computer which touches it?

  • Referencing groups/classes from Puppet dashboard in my site manifest

    - by Banjer
    I'm using Puppet Dashboard as my ENC and I'm not sure how to reference or use class and group classifications from /etc/puppet/manifests/site.pp. I have two groups defined in the dashboard: CentOS6 and SLES11. What should my site.pp look like if I want to include a certain list of modules in the CentOS6 group and a certain list of modules in the SLES11 group? I'm trying to do something like this: # /etc/puppet/manifests/site.pp node basenode { include hosts include ssh::server include ssh::client include authentication include sudo include syslog include mail } node 'CentOS6' inherits basenode { include profile } node 'SLES11' inherits basenode { include usrmounts } I have OS-specific case statements within my modules, but there are some modules that will only be applied to a certain distro. So I suppose I have two questions: Is this the best way to apply modules/resources in an OS-specific manner? Or does the above make you want to vomit? Regardless of #1, I'm still curious as how to reference classes, groups, and nodes from Dashboard within my manifests. I've read the External Nodes doc, but I'm not seeing how they correspond to manifests. Thanks all.

  • passing on command line options in bash

    - by bryan
    I have a question. I have a script, a kind of long script written in bash aprox. 370 lines. That has several functions and in those functions the user has to enter information which is then stored in files. ( This is suppose to represent a MySQL database, with the functions INSERT, UPDATE, SELECT, SELECT where x=y.) I created this myself in bash, now the only thing that rests me is that I need to be able to pass arguments on the command line to the script, that will do the same as the script does. I know that bash has positional parameters such as $1 $2 $3 $* $@ $0 ( refers to the name of the script) etc. I know how I can use these parameters in a simple if function. This is not enough for my script. I basicly need to do the same thing that the script does, but then from the command line. I have been struggling with this for a couple of days now and I cannot think of a way to get it to work. Maybe someone here can help me with this? If you want to have the script. That can be possible, but I don't think I can paste it in here... EDIT: Link to script, http://pastebin.com/Hd5VsDv2 Note, I am a beginner in bash scripting. EDIT: This is in reply to Answer 1. As I said I hope I can just replace the if [ "$1" = "one" ] ; then echo "found one" to if [ "$1" = "one" ] ; then echo SELECT where SELECT is the function I previously had in my script(above) http://pastebin.com/VFMkBL6g LINK to testing script

  • Application to automate Windows software installation in a test lab

    - by Marc
    I have several test environments (hyper-V) which contain a variety of windows servers. Each machine needs periodically rolling back to a given snapshot and then re-installing with the latest version of our software to test. The software installs are quite complex MSI's with a fair few option screens. I know that the installs can be driven from the command line, passing in parameters to override the wizard options. At the simplest level I suppose I could just write a batch file to kick off each install with the required parameters, however the values that are passed in do need to change from time to time (and environment to environment) so a tool with a config file and simple GUI seems like a better idea. I think what makes it slightly more painful is the multiple environments. For example one environment might contain 4 servers and need a config file with all the server names, service endpoints etc. Another environment might be a 1-box install with all names and endpoints set to localhost. So, ideally I want to be able to store different setup configurations and use them to run all the required installers with the relevant settings against the relevant machines. Before I go off to write the thing, does anyone know of an existing, simple, free tool that will let me achieve this?

  • postfix smtpd rejecting mail from outside network match_list_match: no match

    - by Loopo
    My postfix (V: 2.5.5-1.1) running on ubuntu server (9.04) started to reject mail arriving in from outside about 2 weeks ago. Doing a "manual" session via telnet shows that the connection is always closed after the MAIL FROM: [email protected] line is input, with the message "Connection closed by foreign host." Doing the same from another client inside the LAN works fine. In the log files I get the line "lost connection after MAIL from xxxxx.tld[xxx.xxx.xxx.xxx]" This is after some lines like: match_hostaddr: XXX.XXX.XXX.XXX ~? [::1]/128 match_hostname: XXXX.tld ~? 192.168.1.0/24 ... match_list_match: xxx.xxx.xxx.xxx: no match which seem to suggest some kind of filter which checks for allowed addresses. I have been unable to locate where this filter lives, or how to turn it off. I'm not even sure if that's what's causing my problem. Connections from inside the LAN don't get disconnected even though they also show a "match_list_match: ... no match" line. I didn't change any configuration files recently, below is my main.cf as it currently stands. I don't really know what all the parameters do and how they interact. I just set it up initially and it worked fine (up to recently). smtpd_banner = $myhostname ESMTP $mail_name (GNU) biff = no readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/server.crt smtpd_tls_key_file=/etc/ssl/private/server.key #smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_sasl_auth_enable = no smtp_use_tls=no smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth myhostname = XXXXXXX.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = XXXX.XXXX.com, XXXX.com, localhost.XXXXX.com, localhost relayhost = XXX.XXX.XXX.XXX mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.1.0/24 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = #smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_ when checking the process list, postfix/smtpd runs as smtpd -n smtp -t inet -u -c -o stress -v -v Any clues?

  • How to read cell data in excel and output to command prompt

    - by Max Ollerenshaw
    Hi All, I'm a sys admin and I am trying to learn how to use powershell... I have never done any type of scripting or coding before and I have been teaching myself online by learning from the technet script centre and online forums. What I am trying to accomplish is to open an excel spreadsheet get information from it (usernames and password) and then output it into the command prompt in powershell. When ever I try to do this I get an Exception calling "InvokeMember" anyway, here is the code I have so far: function Invoke([object]$m, [string]$method, $parameters) { $m.PSBase.GetType().InvokeMember( $method, [Reflection.BindingFlags]::InvokeMethod, $null, $m, $parameters,$ciUS ) } $ciUS = [System.Globalization.CultureInfo]'en-US' $objExcel = New-Object -comobject Excel.Application $objExcel.Visible = $False $objExcel.DisplayAlerts = $False $objWorkbook = Invoke $objExcel.Workbooks.Open "C:\PS\User Data.xls" Write-Host "Numer of worksheets: " $objWorkbook.Sheets.Count $objWorksheet = $objWorkbook.Worksheets.Item(1) Write-Host "Worksheet: " $objWorksheet.Name $Forename = $objWorksheet.Cells.Item(2,1).Text $Surname = $objWorksheet.Cells.Item(2,2).Text Write-Host "Forename: " $Forename Write-Host "Surname: " $Surname $objExcel.Quit() If (ps excel) { kill -name excel} I have read many different posts on forums and articles on how to try and get around the en-US problem but I cannot seem to get around it and hope that someone here can help!

  • Adding a GET parameter to URL causes 404 error

    - by Adrian Grigore
    I'm trying to install the syntaxhighlightter evolved plugin to my wordpress blog. I've uploaded and activated the plugin, but it did not work. I've looked into the page source code and found out that the plugin style is loaded from the following URL: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css?ver=2.0.320 This causes a 404 error (page not found). The strange thing though is that when I remove the GET parameters, the CSS loads ok: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css What could be causing this problem and how can I fix this? Unfortunately I don't know how to make wordpress drop the GET parameters when loading the stylesheet. EDIT: As I just found out, this happens only in Firefox (3.0.11). IE loads both URLs above just fine. Not that this would be of any help though, so any suggestions would be appreciated. SECOND EDIT: I tried this on my laptop and it works fine with Firefox 3.08. So this really seems to be a browser problem after all.

  • Random Excel bug when referencing a different sheet

    - by Matteo
    I am getting a very strange error anytime I try to use a formula pointing to a cell in a different sheet from the active one (even as simple as "=Sheet2!A1"). This started happening all of a sudden, and without any change in the system - only I seem to having started having the problem since I started using a workbook from another colleague with the same issue. I'm running Excel 2003 SP3 on XP. With little variants, whenever I reference a cell in a different sheet, from any formula, and then press Enter, the formula gets written on a different cell from the one I was editing it in, and throws a REF error. Example: I start editing in cell A1 of Sheet 1, type "=", then move the cursor to cell B2 of Sheet 2 (that may contain any value), and press Enter. At this stage you would expect cell A1 in Sheet 1 to contain formula "=Sheet2!B2" and display the value in that cell. Instead what happens is that the cell remains empty, and another random cell of Sheet 1 gets populated with something like "=Sheet2!#REF!" throwing an error. Interestingly, the error does not happen when I manually type the cell reference in (ie. without moving the cursor to the second sheet). Hope this is making any sense - any ideas are welcome! Thanks.

  • mkfs Operation Takes Very Long on Linux Software Raid 5

    - by Elmar Weber
    I've set-up a Linux software raid level 5 consisting of 4 * 2 TB disks. The disk array was created with a 64k stripe size and no other configuration parameters. After the initial rebuild I tried to create a filesystem and this step takes very long (about half an hour or more). I tried to create an xfs and ext3 filesystem, both took a long time, with mkfs.ext3 I observed the following behaviour, which might be helpful: writing inode tables runs fast until it reaches 1053 (~ 1 second), then it writes about 50, waits for two seconds, then the next 50 are written (according to the console display) when I try to cancel the operation with Control+C it hangs for half a minute before it is really canceled The performance of the disks individually is very good, I've run bonnie++ on each one separately with write / read values of around 95 / 110MB/s. Even when I run bonnie++ on every drive in parallel the values are only reduced by about 10 MB. So I'm excluding hardware / I/O scheduling in general as a problem source. I tried different configuration parameters for stripe_cache_size and readahead size without success, but I don't think they are that relevant for the file system creation operation. The server details: Linux server 2.6.35-27-generic #48-Ubuntu SMP x86_64 GNU/Linux mdadm - v2.6.7.1 Does anyone has a suggestion on how to further debug this?

  • mkfs Operation Takes Very Long on Linux Software Raid 5

    - by Elmar Weber
    I've set-up a Linux software raid level 5 consisting of 4 * 2 TB disks. The disk array was created with a 64k stripe size and no other configuration parameters. After the initial rebuild I tried to create a filesystem and this step takes very long (about half an hour or more). I tried to create an xfs and ext3 filesystem, both took a long time, with mkfs.ext3 I observed the following behaviour, which might be helpful: writing inode tables runs fast until it reaches 1053 (~ 1 second), then it writes about 50, waits for two seconds, then the next 50 are written (according to the console display) when I try to cancel the operation with Control+C it hangs for half a minute before it is really canceled The performance of the disks individually is very good, I've run bonnie++ on each one separately with write / read values of around 95 / 110MB/s. Even when I run bonnie++ on every drive in parallel the values are only reduced by about 10 MB. So I'm excluding hardware / I/O scheduling in general as a problem source. I tried different configuration parameters for stripe_cache_size and readahead size without success, but I don't think they are that relevant for the file system creation operation. The server details: Linux server 2.6.35-27-generic #48-Ubuntu SMP x86_64 GNU/Linux mdadm - v2.6.7.1 Does anyone has a suggestion on how to further debug this?

  • Live Screencast under Linux

    - by OmnipotentEntity
    I was having some difficulty with running a Live Screencast under Linux. I've found jtvlc and tried using that, but whenever I use it the stream comes out either blank or lagged with extremely high latency. I have a fast internet connection and a fast computer, but am I perhaps taxing it too much? Any ideas on what I could possibly be doing wrong? # 1. Get an account on http://www.justin.tv/ # 2. Copy streaming key from: http://www.justin.tv/broadcast/adv_other # 2. Install VLC: http://www.videolan.org/vlc/ # 3. Get Win/Mac/Lin Stream Client: \ # http://apiwiki.justin.tv/mediawiki/index.php/Linux_Broadcasting_API # 4. Adjust the vlc parameters to your liking and run VLC like this #!/bin/bash cvlc screen:// --input-slave=pulse:// \ --screen-width 1920 \ --screen-height 1080 \ --screen-fps 5 \ -v input_stream \ --sout='#duplicate{ dst="transcode{ scale=1, venc=x264{ keyint=60 }, vcodec=h264, vb=600, acodec=mp4a, ab=32, channels=2, samplerate=22050 } :rtp{dst=127.0.0.1,port=1234,sdp=file:///tmp/vlc.sdp} "}' \ --sout-transcode-threads=4 & sleep 2 # 5.

  • converting to MXF using ffmpeg

  • Unable to connect to second name of Windows 2008 Server R2 machine from XP

    - by Tumba
    I used the command netdom computername /add:newname.domainname.com to add a second name to a server running Windows 2008 Server R2. After restarting the server, I had DNS "A" entries for both names. In addition, the second name was added to HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters\OptionalNames, which I believe should have taken care of any NetBIOS resolution. From my Windows 7 workstation, I can ping both names and running net view on both names reveals the same list of resources. From Windows XP, I can ping both names, but net view only works on the first name. Running net view on the second name returns: System error 52 has occurred. You were not connected because a duplicate name exists on the network. Go to System in Control Panel to change the computer name and try again. What do I need to do to make the second name usable from XP clients? Update: I was able to resolve the problem by adding the REG_DWORD key DisableStrictNameChecking = 1 to HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters, then restarting the Server service. However, I do not understand why this was necessary.

  • Printer Naming Conventions

    - by John
    I am working on building a new AD print server and have been pondering the idea of renaming the printers. Right now we have a mix of names that varies between a mashup of some that reference location, some that reference functional area, and some that are rather generic. Some examples include the following: Dell 5210 - Building Name HP 4350 - Functional Area Dell Color 3100 - Location and Building Number HP 6500 - Mailroom I was curious what other people used to name their printers with. What conventions do you use and how to design a method that will be able to be used for a while without needing to rename them all again. Also, the naming methodology needs to be understandable for regular computing users so that they can relatively easily find the printer that they need. I was looking at some ideas from here, but I was not sure how practical some of them are. Any help that you can provide is appreciated. Note: I have reviewed many of the postings on here in relation to server naming conventions and found that they were not specific enough for the use case I present above.

  • Redirecting a single request to another pages, ignoring www subdomain

    - by Petter Brodin
    I have a site running on IIS 7.5 that does an automatic redirect from 'http://mysite.com/whatever.aspx' to 'http://www.mysite.com/whatever.aspx' On the site, there is a lot of traffic to an old URL that I want to redirect to the front page, index.aspx: 'http://mysite.com/foo/bar/index.cgi%something=asdf&somethingelse=qwerty' The problem is that no matter what I try, I can only get the redirect to work with the www subdomain. If I use the URL without www, I just end up at 'http://www.mysite.com/404.aspx' Any ideas? Thanks in advance for all help! Edit3: it seems like the browser caching the redirect response was messing with me, so edit2 is wrong. See my response below. Edit2: disregard edit1, it doesn't seem like it's working after all. Edit: here's some further info: using this article I've managed to redirect from 'http://mysite.com/foo/bar/index.cgi' to 'http://www.mysite.com/index.aspx', but if I add the query string parameters, it still redirects to 'http://www.mysite.com/404.aspx' Isn't there a way to catch all requests to the cgi file, including query string parameters?

  • Clone Microsoft VM > SharePoint issues

    - by Rob
    Hi, We have an existing (production) Hyper-V VM that I want to clone to create a staging server. This server is NOT on a domain/active-directory - uses all local computer accounts. It is Windows 2008 OS, SharePoint 2007, SQL server 2008, Reporting Services, and some custom line-of-business web-applications. We rename the server etc as per the documentation we have, but are having troubles specifically with SharePoint. Some of the sites do not come up, and some issues adding/updating site settings such as site owners. Does anyone know of a definitive resource to this process? thanks Update: We seem to have most working, but the Shared Service Provider, and the SSP's admin site, are not working. In addition, the custom web-parts that reference IIS Session objects are failing (which seem to be related to the Share Service Provider). All the Windows user accounts for various services are renamed during the server cloning, but the windows account names in SQL server are not automatically changed. We've tried to change them in SQL server but still does not seem to work Seems like allot of work - and am thinking that there must be some guidance out there. also getting this: NullReferenceException: Object reference not set to an instance of an object.] Microsoft.Office.Server.Administration.SqlSessionStateResolver.System.Web. IPartitionResolver.ResolvePartition(Object key) +135

  • Using Active Directory through a Firewall

    - by Adam Brand
    I had kind of a weird setup today where I wanted to enable Windows Firewall on a Windows 2003 R2 SP2 computer that would act as an Active Directory Domain Controller. I didn't see one resource on the Internet that listed what would be required to do this, so I thought I'd list them here and see if anyone has anything to add/sees something that isn't necessary. Ports to Open with "subnet" scope: 42 | TCP | WINS (if you use it) 53 | TCP | DNS 53 | UDP | DNS 88 | TCP | Kerberos 88 | UDP | Kerberos 123 | UDP | NTP 135 | TCP | RPC 135 | UDP | RPC 137 | UDP | NetBIOS 138 | UDP | NetBIOS 139 | TCP | NetBIOS 389 | TCP | LDAP 389 | UDP | LDAP 445 | TCP | SMB 445 | UDP | SMB 636 | TCP | LDAPS 3268 | TCP | GC LDAP 3269 | TCP | GC LDAP Ports to Open with "Any" Scope (for DHCP) 67 | UDP | DHCP 2535 | UDP | DHCP ALSO You need to restrict RPC to use fixed ports instead of everything 1024. For that, you need to add two registry keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters Registry value: TCP/IP Port Value type: REG_DWORD Value data: <-- pick a port like 1600 and put it here HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters Registry value: DCTcpipPort Value type: REG_DWORD Value data: <-- pick another port like 1650 and put it here ...don't forget to add entries in the firewall to allow those in (TCP, Subnet scope). After doing all that, I was able to add a client computer to the AD domain (behind Windows Firewall) and log in successfully.
