• Windows 2008 RemoteAPP client disconnects within a matter of minutes

  - by Jeroen Wilke

  I'm having an odd problem with Windows 2008 TS, and remote applications specifically. The situation is as follows: TS idle timeout is disabled via GPO TS terminating disconnected sessions after 1hr (via GPO) My users can log on to the Terminal server, and get a full desktop, OR via rdp files that give access to a few remote applications. When a user connects to a full desktop, everything is fine and dandy, they will remain logged on indefinately, and when they disconnect the session is terminated after an hour. however, when a user connects using a remote application link, the client seems to disconnect after only a few minutes of inactivity, when you click the window, the session reconnects. EventID's on TS server: 4779: This event is generated when a user disconnects from an existing Terminal Services session, or when a user switches away from an existing destop using Fast User Switching. 4778 : This event is generated when a user reconnects to an existing Terminal Services session, or when a user switches to an existing desktop using Fast User Switching users are connecting directly to 3389, not using a TS-gateway at the moment. This behavior is consistent on different clients that we have, Full desktop is fine, RemoteAPP constantly disconnects. The .rdp file used doesn't list any interesting parameters, aside from what application to launch, and where to find it. Can someone explain to me how there can be a difference in behaviour between full desktop, and remoteapp ? since essentially they use the exact same client ? Regards Jeroen

• Increasing MSSQL/Sage performance with SSD? (Dell PE T410)

  - by Anthony

  I have a client wanting better performance of their Sage (Accpac & CRM) server (v5.5, soon to be v7). It's running on 1 of 2 Hyper-V VMs (Svr2008) on a Dell PE T410 server with 24GB of RAM (1333MHz) & dual quad-core, and both VMs (only their C: drives) are on a single RAID5 array. All clients connect via 1Gb ethernet. The 2nd VM is SBS2008 with 9GB RAM (& all SBS dbs & company data are on a separate RAID5 array), & 3GB RAM for the Svr2008 hypervisor. I've given the Sage/MSSQL VM all the RAM I can (12GB) & SQL RAM caching (~8GB, never exceeds ~7.5GB, eg. entire db can now be cached in RAM) and that's helped significantly. Upgrading the Hypervisor to Svr2012 is an obvious step, but probably not a dramatic improvement? What about an SSD for this Sage/SQL VM (VM = 100GB, <10GB for the actual live DB) ? Can SSDs be put into the SAS hot-swap bays? Or will I have to use the mobo SATA(3Gbps?) ports, or PCI-E SSD card? Should SSDs be RAIDed for this situation? Or is SSD's higher reliability offsetting the need for RAID1/5/10? (I have nightly full disk backups) New territory for me, would appreciate some feedback. Thanks, Anthony.

• SQL SERVER – Speed Up! – Parallel Processes and Unparalleled Performance – TechEd 2012 India

  - by pinaldave

  TechEd India 2012 is just around the corner and I will be presenting there on two different session. SQL Server Performance Tuning is a very challenging subject that requires expertise in Database Administration and Database Development. I always have enjoyed talking about SQL Server Performance tuning subject. Just like doctors I like to call my every attempt to improve the performance of SQL Server queries and database server as a practice too. I have been working with SQL Server for more than 8 years and I believe that many of the performance tuning concept I have mastered. However, performance tuning is not a simple subject. However there are occasions when I feel stumped, there are occasional when I am not sure what should be the next step. When I face situation where I cannot figure things out easily, it makes me most happy because I clearly see this as a learning opportunity. I have been presenting in TechEd India for last three years. This is my fourth time opportunity to present a technical session on SQL Server. Just like every other year, I decided to present something different, something which I have spend years of learning. This time, I am going to present about parallel processes. It is widely believed that more the CPU will improve performance of the server. It is true in many cases. However, there are cases when limiting the CPU usages have improved overall health of the server. I will be presenting on the subject of Parallel Processes and its effects. I have spent more than a year working on this subject only. After working on various queries on multi-CPU systems I have personally learned few things. In coming TechEd session, I am going to share my experience with parallel processes and performance tuning. Session Details Title: Speed Up! – Parallel Processes and Unparalleled Performance (Add to Calendar) Abstract: “More CPU More Performance” – A  very common understanding is that usage of multiple CPUs can improve the performance of the query. To get maximum performance out of any query – one has to master various aspects of the parallel processes. In this deep dive session, we will explore this complex subject with a very simple interactive demo. An attendee will walk away with proper understanding of CX_PACKET wait types, MAXDOP, parallelism threshold and various other concepts. Date and Time: March 23, 2012, 12:15 to 13:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India. Add to Calendar Please submit your questions in the comments area and I will be for sure discussing them during my session. If I pick your question to discuss during my session, here is your gift I commit right now – SQL Server Interview Questions and Answers Book.

• Multiple IPv6 addresses being assigned to single interface

  - by Steven Copestake

  I'm configuring a DHCP scope for IPv6, however all my clients are getting 2 or more IPv6 addresses assigned to the interface. I'm using fda8:6c3:ce53:a890:/64 as the prefix. The scope is on a machine running Windows Server 2008 R2 however I'm looking to roll it out on Server 2012 as well. My clients are getting the following: IPv6 Address. . . . . . . . . . . : 1024::1492:9288:7357:7d30(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890::1(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890:1492:9288:7357:7d30(Pr rred) Link-local IPv6 Address . . . . . : fe80::1492:9288:7357:7d30%10(Preferred) In this example there's no DHCP scope and the machine has a static IP of fda8:6c3:ce53:a890::1. With this in mind where are the 1024 address and the fda8:6c3:ce53:a890:1492:9288:7357:7d30 address coming from?

• Repairing inconsistent pages in database

  - by Raj

  We have a SQL 2000 DB. The server crashed due to Raid array failure. Now when we run DBCC CHECKDB, we get an error that there are 27 consistency errors in 9 pages. When we run DBCC PAGE on these pages, we get this: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (m_freeCnt == freeCnt) failed. Values are 2 and 19. Msg 8939, Level 16, State 108, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (emptySlotCnt == 0) failed. Values are 1 and 0. Since the indicated index is non-clustered and is created by a unique constarint that includes 2 columns, we tried dropping and recreating the index. This resulted in the following error: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is '3280'. The statement has been terminated. However running Select var_id,result_on from tests group by var_id,result_on having count(*)>1 returns 0 rows. Here is what we are planning to do: Restore a pre-server crash copy of the DB and run DBCC CHECKDB If that returns clean, then restore again with no recovery Apply all subequent TLOG backups Stop production app, take a tail log backup and apply that too Drop prod DB and rename the freshly restored DB to make it prod Start prod app Could someone please punch holes in this approach? Maybe, suggest a different approach? What we need is minimum downtime. SQL 2000 DB Size 94 GB The table that has corrupt pages has 460 Million+ rows of data Thanks for the help. Raj

• PDFs and Networked Printers

  - by Bart Silverstrim

  Weird issue. We have users printing to networked windows-shared printers (print server Win2003 sp2). Some users have been reporting recently that they can't print PDF documents to particular printers (two example printers are HP 2430 PCL 6 driver and 4250 PCL 6 driver). At first, we found that on many of these systems the "Everyone" object was added to the permissions for the root of the C: volume but had no permissions checked. We added modify privileges to it (these are Deep-Freeze systems, so modifications to these systems that we don't add as administrators won't matter) and they seemed to be able to print. Perhaps Acrobat Reader was writing a temp file for printing where users didn't have permission, we surmised, and made the change and moved on. Yesterday the user called in saying it's not working still. Looked at it; bring up a PDF, click Print and the reader app says that you have to install a printer. Look at the printers folder (Windows XP workstation), and it has printers installed. Print a test page, return to AcroReader, and it will print fine to that printer. The whole time web pages, MS Office documents, etc. print without issue to the same printers. Has anyone seen this issue with Acro Reader 9 and certain network printer drivers or shares involving HP printers? I'd post this to SuperUser but it seems to be associated with a networked printer issue, seems to affect subsets of users but may be more widespread and our users aren't reporting it to us assuming we just know about it, and I've not found rhyme or reason as to why it's affecting just PDF printing and particular printers. The print spoolers are all running on the workstations and print server without errors being logged so far, but I'm going through the logs now to see if I can find anything out of place.

• SSRS 2005 inaccessible after install

  - by Gabriel Guimarães

  Hi I've just installed SQL 2005 and Database Engine is ok, however I can't access it for nothing. When I go to http://localhost/reports I get this prompt for a username and password and it fails with 401.1. When I tried to disable kerberos on the virtual directories, nothing changed. I've tried changing the auth to anonymous and get: Internet Explorer cannot display the webpage. When I access from another machine, I get the prompt only once and get this error. Internet Explorer cannot display the webpage. Can't access this with IE or SSMS 2005. If I try to access with Management Studio i get this error: TITLE: Microsoft SQL Server Management Studio The underlying connection was closed: An unexpected error occurred on a receive.

• exim4 redirect mail sent to *@domain1.example.com to *@domain2.example.com

  - by nightcoder

  Current situation: We have a VPS that hosts a website example.org. Exim is configured to work as a smarthost. All emails sent through exim are successfully relayed to another mail server (that is working on example.com). Goal: To forward mail sent to *@example.org to *@example.com, i.e. change the recipient's address from *@example.org to *@example.com. Problem: If I send email to address *@example.org, then it seems exim doesn't change the address, it still relays the message to another mail server but recipient is still *@example.org. Maybe the redirect is not applied for some reason. Configuration and logs: /etc/exim4/update-exim4.conf.conf: dc_eximconfig_configtype='smarthost' dc_other_hostnames='' dc_local_interfaces='' dc_readhost='example.org' dc_relay_domains='example.org' dc_minimaldns='false' dc_relay_nets='0.0.0.0/32' dc_smarthost='example.com::26' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='true' dc_mailname_in_oh='true' dc_localdelivery='maildir_home' /etc/exim4/conf.d/router/999_exim4-config_redirect (created by me): domain_redirect: debug_print = "R: forward for $local_part@$domain" driver = redirect domains = example.org data = [email protected] (for now data is set to a specific address for simplicity and testing) exim log when sending email to [email protected] (should be redirected to [email protected]): 2012-03-20 19:40:07 1SA4ud-0005Dw-7k <= [email protected] U=www-data P=local S=657 2012-03-20 19:40:08 1SA4ud-0005Dw-7k => [email protected] R=smarthost T=remote_smtp_smarthost H=domain2.com [184.172.146.66] X=TLS1.0:RSA_AES_256_CBC_SHA1:32 DN="C=US,2.5.4.17=#13053737303932,ST=TX,L=Houston,STREET=Suite 400,STREET=11251 Northwest Freeway,O=HostGator.com,OU=HostGator.com,OU=Comodo PremiumSSL Wildcard,CN=*.hostgator.com" 2012-03-20 19:40:08 1SA4ud-0005Dw-7k Completed So, the address is not changed :( Please help!

• restoring a failed SBS 2000 box...

  - by Brad Pears

  Hi there, I read a post where you had mentioned you have had a PERC card blow up on you in an SBS box... I've got a similar situation where one of my RAID drives failed and then the power supply failed before I could replace the drive... I then replaced the power supply and the failed drive and reconfigured the RAID array. I had a recent full backup of the my Win2k SBS's C: drive stored on my SYmantec backup exec server so I installed win2K server on the c: partition and then once I had that up and running, installed the backup exec agent so as to do a restore of the entire c drive including system state. THis all worked just fine, until I had to reboot. I received an "incorrect drive configuration" error and then it hangs. I figure that likely makes sense becasue I think my RAID array is configured slightly different now in that the partitions may be sizeded ever so slightly differently now than they were before I think... Is there a way I can just restore from my backup BUT maybe exclude some of the registry and hidden boot files it wants to restore so that it is booting with the current configuration now active on that machine - not the pre blow up configuration files? I also read a post that indicated you might have to install the exact same service pack etc... etc.. before attemting a restore but that does not make sense to me being as the entire c drive contents are going to be overwritten by the restore anyway? THe basic OS install is just to be able to get the backup exec agent installed . I can;t understand why one would need to install the exact same SP level. CAn you shed some light on what I might be able to do to get this thing up and running? Thanks,Brad

• How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

  - by Luis Alvarado

  I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

• Slow File Copy observed copying 40GB files across network to iSCSI device

  - by Rick

  Here's a curious ones for the gurus: Setup: Source Machine: Windows Server 2003 R2 machine with local hard drive. VHD file of 40GB. 1 x 1Gbps network card, Cat6 cable, switch. Target Machine: Windows Server 2008 R2 machine with iSCSI connection to iSCSI target on separate machine (1TB, RAID5). 1 x 1Gbps network card, Cat6 cable, connected to same switch as for Source Machine. Second 1Gbps network card, Cat6 cable, connected via isolated switch to the iSCSI target. Switches are Netgear JGS524 model (web managed). If I copy from the Win2003R2 machine to Win2008R2 machine local drive I get 40GB in 45 minutes, 36 seconds. If I copy from the Win2008R2 machine to the iSCSI target (local drive to iSCSI target) I get 40GB in 37 minutes 56 seconds. If I copy from the Win2003R2 machine to the iSCSI target via the Win2008R2 machine I get 40GB in 3 hours, 50 minutes, 24 seconds. All copies were done via the following command issued on the Win2008R2 box: XCOPY <source> <target> /J XCOPY /J - Copies using unbuffered I/O. Recommended for very large files. So, what's the bit I'm missing here? Why does a back-to-back copy take in total 1 hour, 23 minutes, 32 seconds when a "straight through" copy take almost 3 times as long? Switches show no errors, network hovers around the 3% utilisation mark for the duration of the copy (whereas the "back-to-back" copies are around the 25% utilisation mark). What have I missed?

• Error 550 Mail Relay Message Could Not Be Sent

  - by mraliks

  I'm not sure if this is the right area to ask, but here we go. I have a client who has a couple websites on a Windows server with MailEnable as the mail manager. Any emails being sent from the server work great, except when sending to some domains, the message does not go through due to the following error: 12/13/11 01:15:56 ME-I0026: [86476200E5834227A819E6E63E0EFDA2.MAI] Sending message 12/13/11 01:15:57 ME-IXXXX: [86476200E5834227A819E6E63E0EFDA2.MAI] Remote server returned a response indicating a permanent error. Server Response: (550 Relaying not allowed**) 12/13/11 01:15:57 ME-E0036: [86476200E5834227A819E6E63E0EFDA2.MAI] MAIL FROM command Failed. Can anyone give me some leads on how to correct the settings to allow emails to go through properly? In particular, the emails are not going through to a Network Solutions email account and Network Solutions has not been very helpful thus far. In addition, can a domain's DNS settings affect this error? Currently, the domains are hosted by Network Solutions and use the Network Solutions email service to send/receive email. The server is located with a different company and the Domains' DNS points to it. Which mail related DNS entries are allowed or not allowed in this scenario? Thanks

• CPU / Affinity mask problem in SQL 2005

  - by Robert Moir

  Hi folks, Having a problem with a SQL Server which was virtualised. The CPU mask was set on the physical host for some reason and now advanced options are not available. So I need to reconfigure the CPU affinity mask settings - which are advanced options, so this is blocked because of the affinity mask issue. I've tried doing this from the SQL server in single user command line mode, I've googled and found lots of people with similar problems but no real solution. I'm stumped. Any ideas? Sample commands and output from query analyser below. sp_configure 'show advanced options', 1 GO RECONFIGURE WITH OVERRIDE GO sp_configure 'affinity mask', 0x00000000 GO RECONFIGURE GO ----------------------------------------- Configuration option 'show advanced options' changed from 0 to 1. Run the RECONFIGURE statement to install. Msg 5832, Level 16, State 1, Line 1 The affinity mask specified does not match the CPU mask on this system. Msg 15123, Level 16, State 1, Procedure sp_configure, Line 51 The configuration option 'affinity mask' does not exist, or it may be an advanced option.

• Spammer relaying via Postfix mail server

  - by Paddington

  I have a Plesk 9.5 mail server (cm.snowbarre.co.za) on Ubuntu 8.04 LTS which forwards all SMTP traffic to an anti-spam server cacti.snowbarre.co.za. Many times I see the headers on the anti-spam server to contain from addresses not hosted on the mail server and I have checked and confirmed that my server is not an open relay server. How can a spammer be using my server to relay spam traffic? How can I stop this? Open relay test: paddington@paddington-MS-7387:~$ telnet cm 25 Trying 196.201.x.x... Connected to cm.

• 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?

• Windows Server 2008 R2 - Cannot Change DNS Domain Context on Some Machines

  - by Richie086

  So I have a small Windows Server 2008 R2 network consisting of a domain controller, a file server, sql server, etc. All machines are joined to a windows domain (CPUSHIELD.COM) and show up in Active Directory Users and Computers under the Computers OU. Each computer has a DNS record as well that was populated when I joined each computer to the domain. However, when I go to my SQL server VM (which is joined to CPUSHIELD.COM) and try to add domain users or groups to the local users or groups on my file server (which is a physical machine) or my sql server (which is a virtual machine), for some reason I cannot change the context to the CPUSHIELD.COM domain.. For example: Here is the really strange thing, I have two other servers on my network that do show CPUSHIELD.COM in the From This Location field (as I would expect with any machine joined to a domain) and I am able to search the local machine and/or domain for users/groups to add. I have done hundreds of Windows Server 2008 installs and this is the first time I have run into this issue. Any ideas? Let me know if you need more info

• backup of TFS with DPM 2007 - different backup times

  - by user46516

  I have DPM set up to back up my TFS server every 30 minutes, the reason being it's a way better interface than the quirky SQL backup interface. I also do a full backup nightly using an SQL maintenance job. My thinking is I would use DPM to restore my databases in case of losing my database and the nightly full backup would be a "just in case" the DPM restore doesn't work. I was thinking a little harder about this set up today and started to think about the fact that the DPM backup of the individual databases happens at different 30 min windows.. i.e. one happens at 13h30, another at 13h34 etc. Would this difference in time be a problem when it comes to restoring the TFS server? If I restore the databases and they are from different times, will this create corruption with pointers in one database pointing to missing items in the other database.. do the databases even rely on each other or are they completely interdependant. Lastly, how would SQL (log) backup cope with this?

• Hyper-v on 2012R2 startup gen1 vm causes the host to freeze up

  - by sputnik

  I've searched a lot to resolve the following issue, but nothing helped me. My problem is, that starting up a first-gen vm locks up the whole host. Only a hard reset helps. Second-gen vm starts and runs perfectly. The freezes happened on 3 different vms. FreeBSD, Ubuntu, Windows Server 2008R2, while Windows 8.1 on second gen config works perfectly. Im using this pc mainly as a workstation. No eventlog errors nor dumps are generated. My system: Windows Server 2012R2 FX-8350, non OC ASRock 870 Extreme R2 (Crappy board imho) 32GB DDR3 1866@1600 (My motherboard, against the "support" for 1866ram won't work with full speed) 120GB SSD 4.5TB Storage space device I dont think that its due to my system, because vmware workstation was running without problems. Did I forget to configure something? Any help is appreciated. P.S: Even deactivating C1E, C6, C&Q didnt work. P.P.S: With no virtual network adapter set, the system still locks up. Creating a first gen vm without any hdds and network and launching works. Attaching a boot dvd causes the host to freeze. The host freezes as the gen1 vm begins to boot, doesn't matter if from dvd or hdd

• Outbound mail issue during Exchange 2003 migration

  - by user27574

  Dear all, I am having an outbound email issue during the Exch 03 migration. Basically, we are migrating Exch03 to new hardware, both servers are Server 03 based. Everything runs smooth while setting up and installing Exch 03 on the new box. Public folders are all replicated. My issues are shown below.... 1) After starting to move users' mailboxes to new Exch 03, they receive some undeliverable mail and bounced back mail from some vendors, then I move few users back to test around, they have no problem at all after moving back to old Exch 03. 2) Another issue is our company has Blackberry users, we don't have BES. Under each user's mailboxes, we have forward rule setup, so that both user inbox and BB can receive email. User who is moved to the new Exch 03 server, they can only send email to the BB user's inbox, mail cannot be forwarded to BB at all, smtp queue stacks up and keep trying until the time is expired. Since not all emails that the users send out from the new Exch have problem, I am not able to narrow down what is the issue here. Can anyone give me some ideas? Could this be MX record / Reversed DNS relate? Or firewall NAT rule setting? Thanks.

• Windows Domain Chaos - Any Solving Approach

  - by Chake

  we are running an old Window 2003 Server as Domain Controller (DC2003). To safely migrate to Windows 2008 R2 we added a 2008 R2 (DC2008R2) to the domain as domain controller (adprep etc.). After dcpromo on DC2008R2 everything seemed to be ok. The new DC appeared under the "Domain Controlelrs" node. It wasn't checked at this time, if DC2008R2 can REALLY act as domain controller. Later we tried to shutdown DC2003 and ran into a total mess with non functional Exchange and Team Foundation Services. After that I got the job to fix... First i thought it could be an Problem with DC2008R2. So I removed it as Domain Controller and installed a new Windows 2008 R8 Server DC2008R2-2. I ran into similar Problems. I tried a bunch of stuff, but nothign helped. I won't list it, maybe I made an mistake, so I'm willing to redo it with your suggestions. To have a starting point I tried the best practise analyser whicht ended up with 24 "Compatible" and 26 "Not Compatible" tests. From these 26 tests 19 read the same. (I'm translating from german, so that may to be the exact wording) Problem: Using the Best Practise Analyser for Active Directory Domain Services (Active Directory Domain Services Best Practices Analyzer, AD DS BPA) no data can be be gathered using the name of the forest and the domain controller DC2008R2-2. I appreciate any suggestions, this really bothers me.

• Mail Scanning System

  - by Mr D

  In the same way gmail can generate ads based on email content, I am looking for a way to develop a system which can: Allow users to connect their email address to our site It then would continously monitor all incomming emails From the incomming emails there would be a critera(e.g. a certain address or subject) if any of the emails matched the critea it would would be saved to a database Then once a new email had been found the users would receive an email notification will tells them to log back into the site to see it. My questions are: Would this be possible? What would be a good language to use(generally I like php, python and java) Are there any frameworks which would help do this? How would I connect the users email account to allow access to their emails(do I need a mail server?) Any advice? Thank you! If you need more information please let me know.
