I have IIS 7 which runx in 64 bit windows server 2008

I am openning [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters]

I right click on parameters select new dword 32 bit value I name it to

MaxFieldLength (I select hexadecimal) enter fffe which is 0x0000fffe (65534)

MaxRequestBytes (I select hexadecimal) enter 1000000 which is 0x0000fffe (16777216)

UrlSegmentMaxLength (I select hexadecimal) enter fffe which is 0x001fffff (2097151)

as it is in image https://dl.dropbox.com/u/541519/fb/reg.png

I restart the server and still I only see up to 260 characters. What am i doing wrong

I have also opened iis to set request filtering to correct values (query string ->enable settings 2097151 for max url length, max query string)

You can probably solve this using a custom webHttpBinding.

<bindings>
    <webHttpBinding>
        <binding name="longbinding" maxUrlLength="32766 />
    </webHttpBinding>
</bindings>

And then use it for your endpoint

<endpoint kind="webHttpEndpoint"
    contract="DToolsSynchronizationService.ISyncService" 
    bindingConfiguration="longbinding"/>

You may need to configure the binding further, but this should be a start.
