    in reply to: Data Deduplication #383596

    Re: Data Deduplication

    I know what was wrong..

    I didn’t set the files older “0” and the default was set to “3” !

    Thanks your the man!!!

    Just re-read some more info on TechNet and found this…

    “If you set MinimumFileAgeDays to 0, deduplication will process all files, regardless of their age. This is suitable for a test environment, where you want to exercise maximum deduplication. In a production environment, however, it is preferable to wait for a number of days (the default is three days in Windows Server 2012 R2 and five days in Windows Server 2012), because files tend to change a lot for a brief period of time before the change rate slows. This allows for the most efficient use of your server resources.”

    Re: Data Deduplication

    Can anyone give this a try? It will only take about 15-20 minutes from enabling the feature, transfer some files and test it :mrgreen:

    Thanks!

    Re: Data Deduplication

    The virtual server mostly set it up as default.

    Installed the server with 2012 R2 image from Microsoft site (Not some dodgy one :mrgreen:).

    Spec:
    2 vCPU
    4GB RAM
    15 GB SCSI (C: – Boot disk)
    30GB SCSI (K: – Data Drive)
    All settings are default

    Windows Server – new server, apart from data deduplication service is enabled.

    It’s really odd… I have visited different blogs and tutorial sites and they have pretty much the same information on how to set this up, but my server just dones’t perform what it’s told lol :-?

    Cheers, looking forward to your result!

    Have you configured dedup properly?

    This doesn’t mean it is actually configured properly.

    Its been a while since i’ve done it and configured it and i don’t have a system available to test at the moment but this technet article should help

    Hi,

    I have followed the instruction/step by step to configure the server, have used PowerShell and Server Manager to configure Data Deduplication.

    The only thing I can think of is, I am doing this in VMware workstation environment…

    Re: Data Deduplication

    Hey, thanks for the speedy reply.

    I am trying different things now. Sorry, forget about the .exe files as I have deleted the volume and now I am using a bigger storage (30GB) and with bigger files to see if it will make any difference, but nope :-?

    Currently I’ve got 4 identical .iso (Windows Server 2012 R2) and all located in the root directory of the volume (K:)

    Re: Data Deduplication

    Hi,

    The files are same, all .iso files. Double checked they are in the supported list.

    Just created a Storage Pool, a virtual disk, make it as a volume and put loads of .iso files in the volume but still no luck! :neutral::confused::confused:

    30GB of virtual SCSI disk
    Used space: 15GB of .iso files

    Windows Server 2012 R2

    in reply to: TLS Help #282985

    Re: TLS Help

    It will make a very big difference in testing, but functionally it wont matter. You will need to test it directly with its own FQDN , not those in MX.

    If you have OWA as well you can see it in a browser, using HTTPS, since a cert is per machine, not service.

    Re: TLS Help

    Is your filter outbound or inbound.
    I suspect its inbound, in that case that is where your MX is pointing to for inbound filtering. All the logs will then show the TLS configuration of the filter service and none of your server.

    So once the second server has a cert I wont need to get another? Is that what you are saying?

    Correct its one cert per server. Pretty sure you will need to reissue it when you move it from one server to the other.

    If your cert name matches your FQDN then your TLS “score” is improved. However technically its not required for TLS.

    I like http://www.checktls.com/ to make sure all my ducks are quacking OK.

    Re: TLS Help

    The domain name would be the external FQDN of the email server.

    If you have Iphones, etc.. already attached, does that mean you have an SSL cert now?

    Re: cant access internet when vpn to sbs2003

    Its nothing to do with the server, rather go to the VPN network adaptor.
    Right click, properties, networking tab, select Internet protocol, click properties button, click advanced button, uncheck “Use Default gateway on remote network”
    Click ok all the way out.

    Thanks! That’s a great resource (and is now bookmarked), but it is still like getting someone to sit the exam for you. I would like to see a clear document that explains how to manually construct the SPF record.

    Personally, I would like to be in a position to be able to see when an SPF record has been incorrectly created.

    Yep, its totally cheating!

    Not sure you would know for certain if the SPF record is incorrect, since you would need intimate knowledge on the mail flow of that organization. But if you enter any domain in the original link I posted, it will give you a feedback based on whatever is listed in that domains live DNS right now.

    Also note, that if your inbound and outbound email servers are the same, you only need to include ‘MX’, no need to hardcode the full IPs. I seen many that add both mx and the IPs of the mail servers; no need for that.
    Similarly if your web server (A) sends email, you can just include ‘A’ that way even if you change webservers, mail sent from it will be still legit.

    Some useful links for learning the hard way :)

    in reply to: SPF Records… #282976

    Re: SPF Records…

    if you are writing it by hand you are doing it wrong, there are many SPF generators.
    By far my favorite is below. or just search for “Microsoft SPF”

    The best part is after you edit your dns and come back it will grab that and make sure its correct and allow you to make edits.

    You may need to adjust your NIC binding order
    if you go to Control PanelNetwork and InternetNetwork Connections

    Then AdvancedAdvanced Settings
    Move up (or down) the NICS in order they should be accessed. Not sure if it applies but is something to check.

    If you want some kind of round robin, make the priority the same, but increasing the distance in numbers makes no difference..

    Host1 with MX value 10
    Host2 with MX value 10
    Host3 with MX value 30 (700)

    Also some spam tactics will go to the highest MX first anyway

    touché.

    But spamhaus is not like the rest. Its the only one I would ever use, 30 min TTL….

    The others can be a nightmare. Most notably sorbs, dont ever use them. They suck so much I want them to fail and go away. Unfortunately they are making loads of money by holding people hostage, they are not a reputable RBL and spoil it for the rest of them………but many use them :-x

    Anyway, NDR sorry for hijacking your thread a bit.

    Vamsoft seems to use spamhaus as well. If you had an issue, how fast would they refer you to spamhaus to remove the blocked IP…? They seem to have a winning combination of spam filtering, I like that, just saying that RBL are probably the most effective first level spam control, and you can get that alone at no cost.

    I know you don’t like it, but you seem to be using it. :shock:

    I have heard some wild speculative rumor, that windows 8 is meant to be used with kinect, like from xbox…..that would be very interesting. The metro thing, which I currently HATE, might actually work well that way. Aside from metro thing its quiet snappy and I love it.

    Re: Reverese NDR attack – change IP/MX records

    Well before you begin, (not sure if you did already or this is a plan) drop the TTL on all public DNS records that you will be updating. This will reduce the change time, when you actually need them to change quick, then raise them back up to a 1 day or so, once the drama subsides.

    Also if you SPF in place you might not have had to deal with the banning in the first place, since there is a mix of domain AND ip to get on the big mailers blacklists. Yahoo is the worst……

    EDIT: Woops never mind SPF wont help, got confused

    Re: antivirus… is it always necessary ?

    On all workstations, including my own, I have AV. Just in case, its never slowed me down, so why not.

    But on servers, I have not have AV installed for many years. There is generally no user login, and AV on a server has caused me lots of headaches.

    Certainly everyone has their stories, but along with best practices and division of credentials, its just unnecessary. ………and clients are prohibited to login on a server, it voids the warranty :)

    When did this start? is there any AV scanning of attachments perhaps?
