  • Concerns about a Dedicated (Windows Server 2008) + DDoS

    - by TheKillerDev
    I am have today a dedicated server with these specs: Intel Core i5 750, 2x120GB (ssd + raid), Windows Server 2008 Web, 200Mbps Network, 24 Gb DD3 And I would like to know what are the best thing I can do to prevent a DDoS Attack, since I know this will be a real threat by the importance of the files that will be archived in it. Today I have apache listening port 80 and RDC listening port 3389. But the security is beeing made only by Windows Firewall. So, any thoughts on what would be good to prevent from DDoS attacks?

  • IBM x226 server with Windows 2003 freezing and showing one HDD degraded

    - by Zvonko Telefonko
    We have an IBM x226 server with Windows 2003 running on it. For weeks it's been very slow and it freezes at least once each day. At the boot it show message "degraded" for one HDD and optimal for other HDDs. We have 4 HDDs in it set up in Raid 1. HDD 1 - HDD 2, HDD 3 - HDD4. It seems that HDD2 is the one who is causing problems (showing degraded status). There's an amber led blinking on it together with the green one. We installed ServerRAID manager downloaded from IBM and it gave us option for "rebuild". But the server froze at some point and now it's rebuilding from start again. I've done some Googling and it says that it could be to failing HDD or some cache battery. How can we verify what is the cause of this?

  • Can't set up IIS Web Server on Server 2008 x64 correctly (what have I missed?)

    - by balexandre
    Using a VM I installed Windows 2008 Server x64 and as the image below shows, added the IIS Role full image and assigned all role features of IIS full image But if I have an ASP.NET (aspx) page that does (C#) Session["test-session"] = "A"; and read in other page I always get nothing! NOTE: I do have an entire ASP.NET web application, the example above is to be succinct and explicit on what is the problem I'm facing. Can anyone know what do I have to do to the Server, so I can use the Session variables? All help is greatly appreciated, Thank you

  • Optimal Disk Setup for OLTP SQL Server

    - by Chris
    We have a high transaction (lots of reads and writes) database server (running SQL 2005) that is currently set up with a RAID 1 OS partition (C:) and a RAID 5 data/log/tempdb partition (D:). The C: has 2 drives and the D: has 4 drives. The server has around 300 databases ranging from 10MB to 2GB in size. I have been reading up on best practices for partioning the disks, but would like some opinions on our setup since we are so limited in the number of disks. It seems like RAID 10 is popular, but I dont think we could use it with only 6 total disks to work with. Thanks. Update I went with 3 RAID 1 Partitions (2 disks each) Partition 1: OS, TempDB, Backups Partition 2: Logs Partition 3: Data

  • File store: CouchDB vs SQL Server + file system

    - by Andrey
    I'm exploring different ways of storing user-uploaded files (all are MS Office documents or alikes) on our high load web site. It's currently designed to store documents as files and have a SQL database store all metadata for those files. I'm concerned about growing out of the storage server and SQL server performance when number of documents reaches hundreds of millions. I was reading a lot of good information about CouchDB including its built-in scalability and performance, but I'm not sure how storing files as attachments in CouchDB would compare to storing files on a file system in terms of performance. Anybody used CouchDB clusters for storing LARGE amounts of documents and in high load environment?

  • Password recovery of a Windows 2003 DNS server.

    - by KronoS
    I'm not going to lie, I feel like an idiot and would probably downvote this myself if I could, but here's my problem. I've just setup a Windows 2003 server as the DNS/AD for a replace of an old server. However, it appears that I don't know the password for the Administrator account. I entered the password and I setup the role, but apparently what I remember/wrote down and what I typed in are different. How do I recover a password? I can't log-on locally as it will only allow to log-on to the newly created domain.

  • Mail sending program & exchange server

    - by Emre
    Hi, I have been asked to send about 6500 e-mails to addresses in a member database. I have written the program, that sends and reports the ones that couldn't send etc. But my concern is that this program will just call smtpclient.Send(); and I don't know what happens if 6000 mails are in the queue. Server is MS Exchange as I have been told. Note: I am planning to send them, say 500 by 500. But what if an exception occurs on the Exchange server at 120... then what happens to the other ones.. I will appreciate little insight to the subject. Thanks in advance.

  • Cisco NAT + IPSec + Web Server Configuration Question

    - by zagman76
    Hello - I currently have a Cisco 881W, and it is configured with one of our static IPs to do basic NAT for the network. We also have a web server that needs it's own IP. I configured the NAT for the 2nd IP, however now traffic through our IPSec VPN doesn't route to the web server properly (well, it routes to the internet, rather than through the Tunnel). I followed the instructions here: http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080094634.shtml But now the outbound NAT doesn't seem to be working properly - it keeps going to the NAT of the Cisco, and not the designated IP address. If anyone can assist, I would appreciate it greatly. Let me know what you need, and I'll get it to you! Thanks!

  • Deny login from certain hosts if logging in with specific sql credentials

    - by Dave
    I want to stop some of our developers from connecting to the production sql server using a specific sql account. They have rights to connect through windows authentication with lower rights. They claim that changing the password will affect too many other processes running on our processing machine. So I want to deny access if they're connecting from there dev machines for now. Another way this would work is if I could just allow connections from one specific host.

  • Uninstall SQL Server 2005 Express after Demoting the DC

    - by Walter Aman
    A Windows Server 2003 SP2 hosting a now orphan installation of SQL 2005 Workgroup was pressed into service as a DC in a disaster recovery scenario. It has since been demoted. The server also hosts legacy apps for which we lack reinstallation resources; thus our desire to preserve it as close to intact as possible while removing the orphaned roles. All efforts to remove SQL 2005 thru Control Panel and ARPWrapper /remove fail with error 29528. Should I abandon this and leave the orphan SQL dormant, or is it reasonable to remove it post-demote?

  • SQL Server Authentication vs Windows Authentication

    - by Nandu
    Hi, I am a SQL Server newbie and would really appreciate any help. I have created a new login (test2) with sql server authentication and granted select & vierw definition permission on another schema (test1) to test2. I am however not able to see the objects of test1 in the object explorer. However I can select the objects from the Query Window. Since this new login is being used to develop reports the user would like to view the objects in the Object Explorer. Another user test3 created using windows authentication and similar permissions is able to see test1's objects in the explorer. Please let me if this is the cause and if not how can help test2 see the objects in Object Explorer.

  • Own hosting, own domain on Virtualbox Ubuntu server - dynamic IP

    - by Pawel
    Hi, I have bought my TLD domain, say domain.com. What I'd like to do is to host the website available under this address on my own computer. I'm assigned a dynamic IP, and I'm also behind a router in my local network. I'd run sites on my ubuntu server on a virtualbox machine which is available in my local network. Preferably, I'd like to have my own domain on some server, with which I could experiment as much as I need (so it's only for educational purposes), but I can't afford to buy such a service. Is it feasible? Can you provide steps I'd need to take to configure it (could be just general explanation). I'd need some guidance, please.

  • incorrect DNS entries on server 2008 r2

    - by user137841
    On the main DC (windows server 2008 R2 standard) in our network I have to clear some old DNS entries every now and then in the Forward and Reverse Lookup Zones. I have set the server Aging/Scavenging settings to Scavenge stale resource records, with both the No-refresh interval and Refresh interval to 5 days. Yet every now and then I still have to logon to the sever and remove the DNS entries for computers that is not part of the domain anymore or has been renamed ect. Is there a different way to automatically remove the old entries?

  • Windows 2003-R2-Server: Process "System" takes large chunks of CPU time

    - by Dabu
    I have a domain controller running 2003 R2. The server behaves very well when restarted daily, however, each day it is not restarted, there's a process called "System" that takes enourmous chunks of CPU time (up to 95%). The server supports AD, WINS, DNS, has Kaspersky Endpoint Security running, and manages backups via Arcserve 15. When I tried so far: Process Explorer (ex-Sysinternals) shows that the "System" process has no sub-processes. In the "Threads" tab of the detailled view I can see that 90% of the CPU time is used up by "ntkrnlpa.exe+0x803c0". The "Interrupts" process is running at 3-5% of CPU time, I'm not sure if this accounts for the amount of CPU time that System takes.

  • Windows 2003 Server Intermittent DNS Issues

    - by Mike
    Looking for a little help here. I have a Windows 2003 DNS Server set up on our network. Lately computers on our LAN have been, at times, unable to resolve a certain sub domain for our website whereas other times the request is resolved just fine. During these periods of "downtime" all other network activity (i.e web sites, internal resolutions, network shares, etc.) remains normal. I can tell it is a problem with our DNS server because the resolution always works from outside our network. I'm hoping someone out there has experienced something similar or could at least offer me place to start troubleshooting. Thanks!

  • Windows file server access control by device

    - by Ori Shavit
    I'm trying to build a system where access to certain resources (file shares) in Windows Server, is limited not only by the username (in a Active Directory domain), but also by the client machine. So far, I haven't found a good way to do this; adding the computer account to the DACL is apparently not the way to do it. Windows Server 2012 supports this with Dynamic Access Control, but this method requires all clients to be Windows 8, it seems, with no way to use this with Windows 7 clients. Is there a supported way to do this? (or alternatively, add support for device authorization with Windows 7).

  • SQL server availability issue: large query stops other connections from connecting

    - by Carlos
    I've got a high-spec (multicore, RAID) server running MS SQL 2008, with several databases on it. I have a low throughput process that periodically needs a small amount of information from one of the DBs, and the code seems to work fine. However, sometimes when one of my colleagues does a huge query against one of the other DBs, I see full CPU usage on the machine, and connections from my app time out. Why does this happen? I would have thought the many cores and harddisks would somehow (together with cleverly written DB server) be able to keep at least some of the resources free for other apps? I'm pretty sure he doesn't use multiple connections for his query. What can I do to prevent this?

  • Protect individual sites on Ubuntu/Apache server

    - by Christoffer
    Hi,?? I need to set up a Apache server configuration for some client sites that run under the same Ubuntu 9.10 machine. All sites are allowed to run PHP, Python and Ruby on Rails. I do not control the source code of these sites and so I need to set up a filter in order to prevent one user to reach files on another users account.?? If I run a script to list files in "/" from one account, I can browse some files and directories in the actual server root. I want to set the root for each account to /var/usersite.com/www/ instead so that listing files in "/" shows the files in the client's root. ??How is this most easily configured??? Cheers!? /Christoffer

  • Restoring a Windows 7 backup onto Server 2008 R2

    - by Colin Desmond
    I have recently moved my main machine from Windows 7 to Server 2008 R2. Just before I did the install, I used the Windows Backup facility to create a backup on a file share. I am now using the Server Backup facility in 2008 R2 to restore this and it is not working. When I use another Win7 machine, I point the restore program at the folder containing the backup fileset and it lets me look through them. In R2, I point it at the same folder and it tells me that "The specified remote share does not contain any backup." I naively assumed that the two systems would be compatible, is this not the case? Is there anyway to get that data back again?
